Abstract

Motion compensation of synthetic aperture sonar (SAS) needs resort to the integrated navigation which can give the position, velocity and attitude of SAS. This paper discussed the inertial navigation system composed of SINS, the Doppler velocity log (DVL) and the high precise quartz depth gauge which acts as auxiliary sensor in vertical. A kind of Kalman filter algorithm for fast tracking is presented in detail. Simulation has been done with the integrated navigation error models of the complex motion of SAS. The simulation indicates that the navigation system is effective and the accuracy of the filter is satisfying. The algorithm can be used in motion estimation of SAS underwater.
