Determining emitter identification information to a desired accuracy

Abstract

A method and system are disclosed for identifying an emitter or transmitter (e.g., among a plurality of emitters) to a desired degree of accuracy. The method or system may receive a signal in a receiver from a transmitter, wherein the signal propagates from the transmitter to the receiver. The method or system may demodulate the received signal to generate a demodulated signal having a carrier frequency of zero and determine a bispectrum associated with the demodulated signal. The method or system may classify the bispectrum into a classification using a neural network having been trained to a signal emitted by the transmitter. The method or system may determine an accuracy of the classification based on a probability of the classification being greater than a threshold.
