Hence, the chirp signal sent on the time Treset is achieved),

from which a plurality N of virtual angle-modulated signals (Liu, p. 3, line 23- p. 4 line 1),

The above offset .sub.g is 0, that is, the cutoff frequency of the signal transmitted by the antenna 2 is equal to the start frequency of the signal transmitted by the antenna 3. The signals transmitted by the antenna 2 and the antenna 3 are adjacent in time and the antenna 2 and the antenna 3 belong to different groups, respectively.
As shown in FIG. 9, the above offset .sub.s is slope*T .sub.s_dwell , that is, the starting frequency of the antenna 1 transmitted signal is the .sub.sum of the cut-off frequency of the antenna 2 transmitted signal and slope*T .sub.s_dwell , or the starting frequency of the antenna 2 transmitted signal is The .sub.sum of the cut-off frequency of antenna 1 transmitted signal and slope*T .sub.s_dwell ; the start frequency of antenna 3 transmitted signal is the .sub.sum of the cut-off frequency of antenna 4 transmitted signal and slope*T .sub.s_dwell , or the start frequency of antenna 4 transmitted signal is antenna 3 .sub.Sum of the cutoff frequency of the transmitted signal and slope*T .sub.s_dwell .

The signals transmitted by the antenna 2 and the antenna 3 are adjacent in time and the antenna 2 and the antenna 3 belong to different groups, respectively ),
and at least one evaluation unit configured to determine at least one object parameter from a radar signal reflected from an object of the surroundings (Liu, p. 3, lines 7-20: The above control unit is also used to control the multiple receiving antennas to receive the signal obtained by reflecting the chirp signal i from the detected object, the chirp signal i being the signal transmitted by the above transmitting antenna i;

the radar signal received by the transmitting-receiving unit (Liu, p. 3, lines 7-20),
wherein the evaluation unitis configured to determine the at least one object parameter using sampling points from within a respective physical signal as well and sampling points within a respective virtual signal (Liu, p. 3, lines 6-20 and line 23- p. 4 line 1).
Regarding claim 2, Liu discloses:
the system according to claim 1 (Liu, Abstract),
wherein the at least one transmitting-receiving unit is configured to adjust at least one of the virtual or physical signals to a specification for a parameter comprising a resolution (Liu, p. 3, lines 6-20 and line 23- p. 4 line 1),

a unique distance (Liu, p. 3, lines 6-20) Examiner interprets target distance as an example of unique distance,
a velocity,
or time-on-target.
Regarding claim 3, Liu discloses:
The system according to claim 1 (Liu, Abstract),
wherein at least one of the physical or virtual signals are modulated in frequency (Liu, p. 3, line 23- p. 4 line 1),
comprising a frequency ramp (Liu, p. 1, lines 5-19: Vehicle-mounted millimeter-wave radar is an indispensable sensor in automatic driving and can be used to provide all-weather obstacle detection. The principle is that the radar sends a frequency modulated continuous wave (FMCW), and the distance, speed, azimuth and other information of the obstacle are obtained by measuring the reflected echo of the obstacle. The FMCW waveform has the function of bandwidth compression, that is, the transmitted signal is scanned through a large bandwidth through chirp, and the received signal and the transmitted signal are mixed to obtain the difference frequency, making the intermediate frequency bandwidth much lower than the transmitted signal bandwidth. The bandwidth of the IF signal is related to the slope of the chirp and the distance to the maximum target, Δf .sub.max = slope*(2*max_range)/c, where Δf .sub.max is the maximum difference frequency, subject to the bandwidth of the IF, and slope is linear continuous frequency modulation The slope of the wave B/T .sub.ramp , that is, the bandwidth B scanned within the time T .sub.ramp , max_range is the distance from the farthest detection target to the radar, and c is the speed of light. At present, the time T (usually 10 to 100 μs) occupied by a fast chirp signal sent by any antenna usually includes the time T .sub.ramp from the linear sweep of the frequency f .sub.start to the frequency f .sub.end , and the T .sub.reset time, Sometimes also includes a period of constant frequency T .sub.dwell . T .sub.reset represents the time required for the end frequency f .sub.end of the transmitted signal to quickly return to the start frequency f .sub.start . This time is because the FMCW waveform needs to be transmitted through a phase locked loop (PLL) to obtain a signal frequency with better linearity. The PLL needs a certain time to stabilize, usually within 10μs. The chirp signal can be sent using the rising ramp shown in FIG. 1 for measurement, or the chirp signal can be sent using the falling ramp shown in FIG. 2 for measurement. Corresponding to the way of ascending ramp, f .sub.start <f .sub.end , for descending ramp, f .sub.start > f .sub.end . Since the time for the PLL to stabilize is related to the bandwidth f .sub.end -f .sub.start , the working time of the device cannot be fully utilized, so the time during T .sub.reset cannot be used for measurement)
Regarding claim 4, Liu discloses:
the system according to claim 1 (Liu, Abstract),
wherein the evaluation unit is configured to determine a distance (d) or a variable based thereon (Liu, p. 1, lines 5-19) Examiner notes distance and speed,
and a velocity (v) or a variable dependent based thereon (Liu, p. 1, lines 5-19),
taking into account a slow-time frequency (fslow) and a fast-time frequency (ffast) and a sweep rate of the virtual signals (pP) and a sweep rate of the physical signals (pR) and a signal duration (TP) of the virtual signals (Liu, p. 8, lines 17-22: Due to the improvement of the PLL's ability, the chirp signal scans hundreds of MHz or even 4GHz bandwidth in the time range of 10～100μs. Due to the Doppler effect, the frequency change introduced within a chirp signal period relative to the target distance can be ignored . Therefore, in a chirped signal, the target distance is obtained by analyzing the frequency of the signal in the intermediate frequency bandwidth. The commonly used algorithm is fast Fourier transform (fast Fourier transform, FFT), where FFT is also called distance-fast Fourier Leaf (range-FFT). The speed information of the target is obtained through the phase change between multiple chirped signals. The commonly used algorithm is FFT. The FFT here is also called Doppler-Fast Fourier (doppler-FFT)) and (Liu, p. 1, lines 5-19) Examiner interprets sweep of frequency as sweep rate of chirp signal,
and the a mean RF transmission frequency (fe) (Liu, p. 3, lines 7-20)
Regarding claim 5, Liu discloses:
the system according to claim 1 (Liu, Abstract),
wherein the at least one transmitting-receiving unit forms a portion of a multi-input multi-output (MIMO) radar system (Liu, p. 2, lines 27-32; At present, the virtual MIMO antenna transmission can use time division, frequency division, and code division. The time division method is the simplest, that is, the transmission antenna transmits chirp signals in sequence, and the signal processing is performed at the receiving end by receiving signals from different receiving channels. However, the time-divided MIMO radar signal is sent in a single ascending or descending ramp, and the time-division antennas transmit signals in sequence (as shown in Figure 3), that is, assuming there are 4 transmitting antennas, and the time for each antenna is T, then The period of 4 transmitting antennas is 4*T. Since there is T .sub.reset time in the transmission of each antenna, a total of 4*T .sub.reset time in 4*T will be wasted and cannot be used for measurement).
Regarding claim 6, Liu discloses:
the system according to claim 1 (Liu, Abstract),

The above offset .sub.g is 0, that is, the cutoff frequency of the signal transmitted by the antenna 2 is equal to the start frequency of the signal transmitted by the antenna 3. The signals transmitted by the antenna 2 and the antenna 3 are adjacent in time and the antenna 2 and the antenna 3 belong to different groups, respectively.
As shown in FIG. 9, the above offset .sub.s is slope*T .sub.s_dwell , that is, the starting frequency of the antenna 1 transmitted signal is the .sub.sum of the cut-off frequency of the antenna 2 transmitted signal and slope*T .sub.s_dwell , or the starting frequency of the antenna 2 transmitted signal is The .sub.sum of the cut-off frequency of antenna 1 transmitted signal and slope*T .sub.s_dwell ; the start frequency of antenna 3 transmitted signal is the .sub.sum of the cut-off frequency of antenna 4 transmitted signal and slope*T .sub.s_dwell , or the start frequency of antenna 4 transmitted signal is antenna 3 .sub.Sum of the cutoff frequency of the transmitted signal and slope*T .sub.s_dwell .

The above offset .sub.g is slope*T .sub.g_dwell , that is, the starting frequency of the antenna 3 transmitted signal is the .sub.sum of the cut-off frequency of the antenna 2 transmitted signal and slope*T .sub.g_dwell , where the antenna 2 and antenna 3 transmitted signals are adjacent in time And antenna 2 and antenna 3 belong to different groups.

For example, the frequency band has gradually evolved from 24GHz to 77GHz/79GHz, and higher range resolution can be obtained through a larger scanning bandwidth. On the waveform, the chirp signal (chirp) scan period is a few ms level, reduced to dozens of μs level, so that the measurement distance and measurement speed are decoupled. This reduces the probability of false targets and effectively avoids non-ideal characteristics near DC. The number of channels has also evolved from a single-transmit multiple-receive (single input multiple output (SIMO)) mode to a multiple-transmit multiple-receive (multiple input multiple output (MIMO)) mode, and the antenna scale continues to expand, making virtual MIMO (Virtual MIMO) obtainable The aperture of the virtual antenna is enlarged, thereby improving the angular resolution).

In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claims 10 and 19 are rejected under 35 U.S.C. 103 as being unpatentable over Liu et al WO , hereinafter Liu in view of Stettiner et al (US 20210156982 A1), hereinafter Stettiner
Regarding claim 10, Liu discloses:
The system according to claim 1 (Liu, Abstract),
Stettiner discloses:
wherein a distance between respective physical signals is non-equidistant (Stettiner, paras [0127], Note, however, that time multiplexed MIMO is associated with several problems including coupling between Doppler and the spatial directions (azimuth and elevation). In one embodiment, this is addressed by applying a nonlinear (e.g., random) order to the TX array element transmission. Starting with a nonlinearly ordered transmit sequence which cycles over all TX elements, then repeats for the CPI duration a ‘REUSE’ number of times. The TX sequence in each repetition is permuted nonlinearly (e.g., randomly). Each repetition uses a different permutation. Thus, it is ensured that each TX element transmits the same number of times during a CPI and that the pause between transmission, per each TX element, is never longer than two periods. This is important in order to keep Doppler sidelobes low. It is marginally beneficial though not necessary to change the permutations from one CPI to the next.
[0128] The decoupling effectiveness is largely determined by the number of chirps in the CPI. Hence, this is another incentive for using short duration chirps. Doppler ambiguities occur at lower target speeds. In one embodiment, this is solved by using a nonlinear (e.g., random) transmit (TX) sequence (as described supra) and by using relatively short chirps. A lower bound on chirp duration is the propagation delay to the farthest target plus reasonable overlap time. In one embodiment, a PRI of seven usec is used to cover targets located up to 300 meters away. Note that shorter chirps also increase the required sampling rate as explained in more detail infra) and (para [0135], Regarding MBC, the total bandwidth is broken into separate yet partially overlapping bands where each chirp has a nonlinear (e.g., random) start frequency and relatively low bandwidth (e.g., 50, 75, 100, 125 MHz). All chirps, once aggregated, cover a much larger total bandwidth (e.g., 1 GHz)) Examiner notes that non-linear or random signals relate to non-equidistant signals.
It would have been obvious to someone in the art prior to the effective filing date of the claimed invention to modify Liu with Stettiner to incorporate the features of: wherein a distance between respective physical signals is non-equidistant. Both arts are considered analogous arts as they both disclose vehicle-mounted radar systems with MIMO. Liu discloses physical (chirps) and virtual signals; however, does not disclose wherein a distance between respective physical signals is non-equidistant as within Stettiner. The modification would render the predictable results of improved angular resolution; improved multi-target discrimination; and improved reduction of false target detection.
Claim 19 is rejected under the same analysis as claim 10.
