DETAILED ACTION
Status of Claims
Claims 1-20 are currently pending and have been examined in this application. This NON-FINAL communication is the first action on the merits.
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph: The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
Claim 12-13 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claim 12 recites the limitation “generate electronic attack strategies to be pursed”. It is unclear what the term “attack strategies” refers to and no support for this limitation can found or implied by the instant specification. The examiner has interpreted this limitation as “generate a response based on emitter data”.
Claim 13 is rejected under 35 U.S.C. 112(b) due to its dependency on Claim 12.
Claim Rejections - 35 USC § 103
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.
Claims 1-4, 7-11, 13-14, 16-20 are rejected under 35 U.S.C. 103 as being unpatentable over Logan (US 20180313880) in view of Hjelmstad (US 20070222672).
Regarding Claims 1, Logan teaches the following limitations:
A system for emitter identification and tracking in an electronic warfare scenario, the system comprising: (Logan - [0014] Aspects of the embodiments are directed to pulse processing systems and methods. An RF pulse in the present context is a burst of energy in the monitored RF spectrum. Sources of RF pulses include communications systems, RADAR, unintentional transmitters such as arc welding tools, other industrial equipment such as microwave ovens, plasma generators, or the like, electronic warfare signals such as jamming signal transmitters, and many others. [0022] The received and digitized pulses are fed to feature correlator 128, which is constructed, programmed, or otherwise configured to extract various predefined features of the pulses and assess correlations between features of various pulses to determine and track one or more emitters of interest. According to some embodiments, feature correlator 128 extracts features such as frequency, bandwidth, pulse width, pulse repetition frequency, I-Q parameters, modulation type, angle of arrival, and the like, and generates pulse descriptor data structures, such as pulse descriptor words (PDWs) for the assessed pulses. As a subsequent layer of correlation, the PDWs are compared to determine any patterns that are indicative of relationships among the PDWs, such as whether certain pulses appear to emanate from a common emitter, such as a RADAR station, communication transmitter, etc. The result of this assessment is an emitter descriptor data structure, such as an emitter descriptor word (EDW) for each suspected emitter. The EDW may include certain features of the PDWs which have been determined to be correlated to a common emitter, for example, along with additional indicia that distinguish the emitter from among other emitters. As a further layer of assessment, the EDWs corresponding to the various emitters are stored in an active emitter data structure, such as an active emitter file (AEF), which maintains and updates features describing a known set of emitters and their various feature sets.)
an antenna array configured to receive signals from radio frequency (RF) emitters; (Logan - [0016] Pulse capture circuitry 102 may include radio receiver circuitry, including such arrangements as super heterodyne circuitry… Pulse capture circuitry 102 may also include analog-to-digital conversion circuitry that performs sampling, quantization, and digital encoding operations to interface the RF receiver circuitry with the signal processing circuitry. Logan does not explicitly teach “antenna array”.)
processing circuitry configured to: convert the signals received from the RF emitters into digital signals; (Logan – [0016], [0027] Pulse processor 135 analyzes the contents of the filtered pulses. [0033] Example computing platform 200 includes at least one processor 202 (e.g., a central processing unit (CPU), a graphics processing unit (GPU) or both, processor cores, compute nodes, etc.), a main memory 204 and a static memory 206,)
determine, from the digital signals, pulse descriptor words (PDWs) that describe characteristics of the digital signals, (Logan - [0022])
classify the PDWs using a combination of unsupervised machine learning and supervised machine learning to form classification results that indicate whether the PDWs correspond to one of a known emitter and an unknown emitter; and (Logan - [0022], [0018] In another type of embodiment, a supervised machine-learning system, such as an artificial neural network (ANN) may be utilized. Other examples include classification engines, such as a K-nearest neighbor classifier, for instance. Unsupervised machine-learning algorithms may also be used.)
update an active emitter data structure of emitter profiles based on the classification results; and (Logan – [0018], [0022] Logan does not explicitly teach “emitter library”.)
a memory configured to store the PDWs. (Logan – [0033])
Logan does not explicitly teach the following limitations, however Hjelmstad, in the same field of endeavor, teaches:
antenna array (Hjelmstad – [Fig. 1], [0003] These systems employ multiple receiving antennas and multiple receivers to derive a course direction to the emitters.)
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the radio receiver circuitry of Logan with the multiple receiving antennas of Hjelmstad in order to derive course direction to an emitter (Hjelmstad – [0003]).
emitter library (Hjelmstad – [Fig. 3], [0022] The processing unit 3 with the A/D converters 24, gate arrays 25 and processor 26, has as its task to filter out all false signal and classify, identify and find the direction to all radar sources observed within it area of sight. This is done in a multi-stage process as illustrated in FIG. 3. The process includes the following steps: [0023] 1. Pulse detection sorting wanted information from noise [0024] 2. Pulse parameter estimation, which is performed on each detected pulse. The estimated parameters may include: [0025] direction of arrival [0026] carrier frequency [0027] pulse width pulse amplitude [0028] 3. De-interleaving. De-interleaving is the process of identifying which of the incoming pulses that come from each of the observed emitters, thus sorting all pulses coming from the same emitter into one (or more) pulse trains. [0029] 4. Emitter analysis and emitter recognition. Emitter analysis means that an improved set of pulse parameters are determined, now sorted per emitter, forming a "fingerprint" characterizing each emitter. The emitters are then identified by comparison with known signatures stored in a database)
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the active emitter data structure of Logan with the database of Hjelmstad in order to perform emitter analysis and emitter recognition (Hjelmstad – [0029]).
Regarding Claim 2, Logan further teaches:

These may include stochastic-type machine learning, as well as neural-network, classification, association rule mining, clustering, support vector machine, or other machine-learning mechanism, whether supervised or unsupervised,)

Feature grader 136 applies pulse-grading criteria 138 along with the temporal-proximity weighting such that features deemed “good” in received pulses tend to elevate the grading, and features deemed “bad” tend to suppress the grading score.)
each of the supervised classifiers configured to use the PDW clusters to generate a prediction of an emitter used to generate the PDWs, (Logan – [0018], [0022])

Logan does not explicitly teach the following limitations, however Hjelmstad, in the same field of endeavor, teaches:

the processing circuitry is configured to use a Mission Data File Free (MDF-Free) approach in which identification and tracking do not rely exclusively on a pre-existing database of emitter characteristics but are based on learned characteristics from real-time data. (Logan – [0018], [0022])
Logan does not explicitly teach the following limitations, however Hjelmstad, in the same field of endeavor, teaches:

Logan does not explicitly teach the following limitations, however Hjelmstad, in the same field of endeavor, teaches:
insufficient initial information… emitter library… medium or moderate probability (Hjelmstad – [0064] Regarding the cluster of five vessels within the cluster cells, the DOA analysis will not discriminate these. Assuming a conservative estimate of the frequency spread, a uniform distribution of carrier frequency over 60 MHz, and a frequency resolution of 1 MHz in the carrier frequency determination in the receiver, there is a 16% probability that two emitters will fall into the same histogram cell. [0065] Thus, the first stage of the recommended de-interleaving process will resolve more than 90% of all vessels in the scenario. In order to increase the quality further, a second stage of de-interleaving is performed on the candidate emitter pulse trains. This stage is based on detailed PRI analysis, analysis of pulse width and antenna analysis.)
