Electronic Sensor Precision Feature Extraction Pre-processor

Historically, most real-time electronic sensor parameter measurement devices have provided estimates of radar frequency, pulse duration or pulse width, pulse repetition interval or frequency, an indication of angle of-arrival or line of bearing, and occasionally scan rate. Newer systems are now incorporating some minimal detection of chirp and phase shift key modulations. The need exists to develop an electronic sensor precision feature extraction pre-processor (ES PFEP) which extracts several additional non-traditional parameters and incorporates them into signals analysis. The ability to provide new discriminants in the characterization of waveforms will significantly increase both the number of applications of and the performance of electronic sensor parameter measurement devices. The ES PFEP will consist of Field Programmable Gate Array (FPGA) core firmware modules to support the extraction and reporting of non-traditional Intentional Modulation-on-Pulse (IMOP) features. These modules will consist of pulse processing algorithms necessary for the detection, down-conversion, demodulation, pulse feature extraction, and Feature Descriptor Word (FDW) generation of intercepted emitter pulses.
