Study on Dynamic Characteristics of Carrier based on Minehunting Sonar Array

The dynamic characteristics of strap down minehunting sonar array on moving base are investigated.Firstly the dynamic models of sonar array are given.Considering the characteristics of three shaft frame and the presence of moving base, it gives emphasis to the analysis and research of the dynamic characteristics of sonar aray. The characteristics of time varying,nonlinear and strong coupling are posted, at the same time, the especial propertices of the inertia matrix are pointed out. Simulations show that the theoretic analysis in accurate.
