摘要:
舰船等航海设备在大海中航行会受到海洋气象环境的影响发生摇荡,其角跟踪性能会受船摇影响,可能难以跟踪目标,需要预先进行模拟分析以减小危害。角跟踪系统模拟船摇时,根据船摇信息,通过对无船摇影响的位置矢量进行欧拉角旋转,得到受船摇影响的位置矢量;利用矩阵变换解算出受船摇影响的轨道参数,进而推导出受船摇影响的和差支路信号功率及相位变化数据,实现船载角跟踪系统模拟器对船摇的模拟。试验表明,模拟船摇并采取相应隔离措施,角跟踪系统能够快速收敛。

Abstract:
Ships and other navigation equipment on the sea will sway due to the impact of marine meteorological environment,the angle tracking performance may be worse because of ship swaying,which makes it is hard to track target.So it is necessary to perform simulations and analysis in advance to reduce the hazard.When the angle tracking system simulates ship swaying,according to the ship swaying information,the position vector affected by ship swaying is obtained through the Euler angle rotation of the position vector without the influence of ship swaying,the orbit parameters affected by ship swaying are calculated by matrix transformation,then the signal power and phase change data of sum and difference branch affected by ship swaying are derived,thus realizing the simulation of ship swaying by the simulator of ship borne angle tracking system.The experiment shows that the angle tracking system can converge quickly by simulating the ship swaying and taking corresponding isolation measures.
