The principle of operation of the device

The principle of operation of the sonar is as follows. Sonar antennas are placed on the carrier. The axis of the directional pattern of the SSS transceiver antenna is directed at an angle of 90° to the line of motion. As a result of sending probing signals and receiving echoes reflected from the bottom, an acoustic image of the bottom is formed on the monitor screen of the complex in the form of two stripes along the course of the vessel (one for the port side, the other for the starboard side). The formation of an acoustic image is due to the fact that as the acoustic signal propagates in the water, it is scattered by any inhomogeneity. The scattering coefficient is different for different types of soils and objects. This leads to the fact that the intensity of the echo signals from different parts of the bottom will also be different, which is displayed on the acoustic image by different brightness points.Objects located in the water column or on the surface of the bottom and caught in the field of view appear on the acoustic image, which allows you to obtain relative exceedances of objects on the bottom, on the basis of which the heights of objects can be approximately estimated.
