FIELD: radio engineering.
SUBSTANCE: during search of broadband signal synchronized filtering is widely utilized. Time of signal accumulation in synchronized filter is limited by non-stability of support generators of transmitter and receiver. That is why to provide for interference resistance of signals non-coherent accumulation of signal is performed. Problem, solved by current implementation, concerns significant decrease of RAM, which is used for storing results of non-coherent signal accumulations, received during scanning of non-determined area and, accordingly, simplification of mobile station. To decrease capacity of noted RAM not all calculable modules of correlation function of received periodic signal are accumulated, but only a limited number of maximal modules.
EFFECT: higher efficiency.
