FIELD: physics.
SUBSTANCE: side-scanning phase sonar includes a radiator, a receiver, a sensor for measuring angle of roll, a control unit and a recorder, connected to a computer; the side-scanning phase sonar further includes a sensor for measuring angle of pitch, a program unit, a reflected signal spectrum analyser, a monitor; the computer is further connected to outputs of a ship echo sounder, a ship satellite navigation system receiver, the sensor for measuring angle of pitch, the program unit and the reflected signal spectrum analyser.
EFFECT: high accuracy of survey.
