Abstract
A method of processing times-of-arrival (TOAs), some representing emitted pulses by an emitter and generated from a pulse pattern having a fixed greatest common divisor pulse repetition interval (GPRI), the method including: creating pulse trains each including an initial TOA and a vector of added TOAs, and a corresponding pulse index vector mapping the TOA vector into the pulse pattern consistent with a known TOA tolerance and viable with a known GPRI range of the emitter type; and walking, for each pulse train, each next TOA after the added TOAs, and each next index mapping the next TOA into the pulse pattern, including checking if the pulse train extended by the next TOA and next index is consistent with the TOA tolerance, checking if the extended pulse train is viable with the GPRI range, and if both checks pass, adding the next TOA and next index to the pulse train.
