    CALIBRATION This chapter contains the procedures for calibrating the system. Overview Calibration is mandatory for acoustic resource surveys. In order to improve data ac- curacy, calibrate the unit with a standard sphere. The purpose of the standard sphere is to calibrate the TX and RX sensitivity of the entire system. The sensitivity correction value is found by measuring the target strength (TS) and theoretical TS of a known target (standard sphere) on the open sea.
