A method of approximate filtration of noise reflections is proposed for measurement of the coordinates of an object with a sound emitter moving in an aquatic environment. A passive hydroacoustic detection and ranging system based on a network of hydrophones is used in the measurements. A two-stage approximation algorithm is employed for digital processing of the Doppler hydroacoustic signals from the outputs of the hydrophones. An example illustrating implementation of the filtration method and its error is considered.
