ECHO SOUNDER Russian patent published in 2020 - IPC G01S15/00 

FIELD: hydro acoustics.

SUBSTANCE: echo sounder relates to hydroacoustic systems for determining depth and can be used for automatic detection of bottom echoes and switching of depth measurement scale depending on current measured depth. Solution of the task is achieved by introducing the possibility of automatic establishment of optimum parameters of the probing pulse and frequency band in the sounder receiver based on analysis of the current depth measured by the echo sounder.

EFFECT: object of the invention is to increase the reliability of the measured depths and to automatically maximize the signal / noise ratio in the sounder receiver in a wide range of measured depths using the echo sounder.
