Study on attitude stabilization coordinate control of strap-down mine-hunting sonar array

Attitude stabilization of sonar array is kept by three axes mutation, the precision of the attitude stabilization will be effected by the coordinate abilities of three axes mutation. So it is essential to study the attitude stabilization coordinate control of sonar array. Firstly, we studied the pointing error model of sonar array. Then, based on the intelligent control, the hierarchical coordinate control of sonar array is proposed and the systematic structure and the coordinate strategy are given in this paper. Finally, we carry out the simulation on the station short distance, long distance and swaying, the results of simulation show that the sonar array with coordinate control strategy of the sonar array operates smoothly.
