Claim Text:
1. A method for detecting and classifying a signal, the method comprising: converting, using a transducer, energy waves in which the signal is carried into an electrical signal; generating, by a receiver in a receiver system, information in response to receiving the electrical signal using pulses and pulse information comprising values for a number of parameters for the pulses, wherein the information is generated using a complex ambiguity function to form a correlation with respect at least one of a differential time offset or a differential frequency offset between information generated and information received by another receiver, and wherein a repetitive portion of the signal carried in the energy waves is detected using the correlation; generating, by the receiver, a number of stochastic histograms using the information generated; accumulating a circular stochastic histogram in the number of stochastic histograms for a parameter in the number of parameters using values for the parameter for the pulses, wherein the parameter is a circular parameter selected from one of an angle of arrival, a phase difference of arrival, or a longitude; and detecting and classifying, by the receiver, the signal using the number of stochastic histograms and the parameter.
