Localization of Random Pulse Point Sources Using Physically Implementable Search Algorithms

Abstract—High-speed algorithms for detecting and localizing randomly distributed pulse point objects capable of generating instantaneous delta pulses at random time instances. The search is carried out using the reception device (detector), which can freely move within the search interval and dynamically adjust the size of the scanning window. In this work the a priori information about the distribution of the sought signal source is limited by the single-mode functions with a stepwise probability density function, which provides that the algorithms are physically implementable. The parameters of the optimal search are computed in dependence on the a priori probability density function of the sought signal source and the required localization accuracy.
