FIELD: measuring equipment.
SUBSTANCE: method relates to active hydroacoustic systems for detecting the bottom and estimating its depth, and can be used in echo sounders for selecting interfering echoes. To achieve this technical result, selection of interfering echoes received along the side directional lobes by time selection of echo signals from the array of echo-signal amplitudes that have passed the threshold processing of the original array of echo-signal amplitudes is performed.
EFFECT: technical result of the invention is to increase the reliability of the depth estimation by the echo sounder in each sensing cycle by selecting the interfering echoes received by the echosounder along the side directional lobes of the antenna.
