1. A method of detecting and classifying received pulses from a plurality of emitters comprising,deinterleaving said received pulses into bands of pulse repetition intervals (PRI'"'"'s) so that a fixed number of pulses are required for detection of an emitter regardless of the PRI of the emitter,determining pulse periodicities of said received pulses by autocorrelation,selecting candidate emitter PRI'"'"'s from said pulse periodicities,time-integrating the pulses of candidate emitters PRI'"'"'s to obtain time-integrated signals,detecting possible emitters from peaks in said time-integrated signals, andconfirming emitter existence by measuring time-continuity of said pulses.
