Abstract

System and method for identifying an RF emitter include: channelizers for channelizing RF signals into several channels; a compressive sensing (CS) encoder for each channel to CS encode the channelized signal to produce an encoded channelized signal in each of the plurality of channels; a summer to sum the encoded channelized signals of all of the plurality of channels to produce an I/Q data; a channelized pulse detection circuit to detect pulses in each channel and produce encoded pulse snippets from the I/Q data; a CS decoder for each channel to CS decode the encoded pulse snippets; a first machine learning device to characterize the decoded pulse snippets and to produce pulse description words (PDWs); and a second machine learning device to associate the PDWs with one or more RF emitters and identify the one or more RF emitters.
