Abstract. The article discusses the results of the development and application of the trajectory-spatial filtering algorithm, which, using the property of spatial selectivity of the combined hydroacoustic (vector) receiver, allowed to isolate the acoustic characteristics of the moving noise source for a long period of time on the background of ambient background noise and suppress the ambient noise sources, which provides a significant increase in accuracy of vector-phase methods to determine the parameters of the primary hydroacoustic fields and coordinates of the radiation zones of mobile marine noisy objects.
Keywords: hydroacoustics, mobile marine noisy objects, processing algorithms, combined hydroacoustic receiver.
