舰艇姿态对作战系统动态对准精度的影响分析

Analysis of Effects on Alignment in Dynamic State Precision of Warship Combat System Caused by Its Attitude

为提高舰艇作战系统动态对准精度,笔者以舰载三坐标雷达为例,研究了舰艇姿态对作战系统动态对准精度的影响。建立了作战系统对准的坐标系,推导了其中主要的坐标转换,计算了舰艇姿态引起的传感器测量误差,分析了舰艇摇摆对动态对准精度的影响,并进行仿真实验。仿真结果表明:舰艇艏摇角造成了传感器测量的方位角误差,舰艇的纵摇角、横摇角造成了传感器测量的方位角和俯仰角误差,但舰艇姿态对传感器的距离测量影响较小。需要在后续的动态对准数据处理过程中对误差进行修正,从而满足舰艇作战系统动态对准的要求。

In order to improve the accuracy of warship combat system alignment in dynamic state, the author has taken shipborne 3D radar as an example to study the effects on alignment in dynamic state of warship combat system caused by its attitude. A coordinate system aligned combat system was established in this paper, the mainly coordinate conversion were derived, sensor measurement errors caused by warship’s attitude were calculated and simulated by computer. Simulation results show that： the warship’s heading angle causes the azimuth angle error of sensor measurements, the warship’s pitch angle, roll angle cause the angle azimuth and elevation angle error of sensor measurements, and there is almost no influence on sensor distance measurement caused by warship’s attitude. Error correction is need in the subsequent data processing of dynamic alignment to meet the requirements of warship combat system alignment in dynamic state.
