Abstract
High-speed algorithms for detection and localization of randomly distributed pulse-point objects capable of generating instantaneous delta pulses at random times are investigated. The search is carried out using a receiving device (detector) that can freely move within the search interval and dynamically alter the scanning window size. In this study, a priori information on the distribution of the sought signal source is limited to single-mode functions with a stepwise probability distribution density, which ensures physical feasibility of the algorithms. The parameters of the optimal search are calculated depending on the a priori distribution density of the sought signal source and the required localization accuracy.
