Due to the moving base existence of the minehunting and the frame structure characteristic of the sonar array , a new modeling thought in which the boat body coordinates is regarded as moving coordinates and the whirligig equation of sonar array compared with the self coordinates is founded on the basis of the euler ' s theorem and the coordinate transform is introduced . the dynamic equations of minehunting sonar array with the state matrix form are founded by settling the dynamic models with the vector form . so it offers theory foundation for analyzing the dynamic characteristic and designing robust control 由于獵雷艇作為動基座的存在和聲納基陣的框架結構特點,提出了以艇體坐標系為運動坐標系,運用變形的歐拉定理和坐標變換建立聲納基陣相對自身坐標系的旋轉運動方程的建模思想;將所建立的矢量形式的動力學模型展開整理,獲得了狀態矩陣形式的獵雷聲納基陣動力學方程,為系統動力學模型的實用化奠定了基礎。
