Abstract:

Propagation Research Associates, Inc., (PRA) proposes to design a receiver that will significantly reduce the sample rate required for a pulsed-Doppler EW sensing application using Compressive Sensing (CS) technology. The PRA Adaptive CS receiver will provide a compression in information space that will be sufficient to characterize multiple pulsed-Doppler waveforms accurately over a relatively large frequency band of interest. A pulsed-Doppler waveform can generally be characterized by a few parameters such as signal frequency, pulse width, pulse repetition frequency, dwell time, and bandwidth. The CS receiver will sample a number of channels (8) at the information rate required to determine the waveform parameters of interest instead of the Nyquist rate. By sampling at the information rate, the Analog-to-Digital Converter sample rates will be reduced by a factor of 50 to 1. An additional signal reconstruction channel (9th channel) will designed that can adapt to the output of the CS receiver to minimize the ADC sample rate. PRA will simulate the CS receiver and demonstrate its capability to (1) characterize pulsed-Doppler waveforms with varying pulse parameters, and (2) reconstruct the signal with minimal ADC sampling.
