Pulse deinterleaving signal processor and method

Claim 1

A pulse deinterleaving signal processor comprising: an amplitude threshold circuit providing an output signal in response to the application thereto of each input pulse exceeding a predetermined threshold; a timing circuit connected to receive the output signals from said threshold circuit and provide a time of arrival signal at an output thereof in response to each output signal received from said threshold circuit; a sampling device connected to receive the input pulses and provide a plurality of samples of each pulse exceeding the predetermined threshold in response to an output signal from said threshold circuit; a transform circuit connected to receive the plurality of samples from said sampling device and provide a plural point transform, spectral signature of each sampled pulse at an output thereof; a memory coupled to the output of said transform circuit for receiving and storing each substantially different spectral signature; a pattern recognizer/correlator connected to receive each spectral signature from said transform circuit and connected to said memory for comparing each received spectral signature with each stored spectral signature to determine pulses from a common source; and logic circuitry coupled to said correlator and said timing circuit for determining the time interval between pulses from a common source.
