Abstract :
The motion compensation of Synthetic Aperture Sonar(SAS) is a important part during the signal processing. The navigation data of position and attitude angle is needed for the motion compensation. In this paper, the Integrated Navigation system of a fiber optic gyro compass(FOGC) and acoustic Doppler current profile(ADCP) is provided to solve the SAS motion compensation. The simulation result shows that navigation precision of the Integrated Navigation system of FOGC and ADCP is satisfied for the short line motion compensation for the SAS. And the Integrated Navigation system is simple and high reliable.
