摘要
多功能相控阵雷达在行进间工作时,载体平台姿态的晃动会使得雷达的点迹测量值和波束指向偏离真实值,存在角度误差,难以满足雷达对目标跟踪精度的要求。针对此问题,提出了一种适用于多功能相控阵雷达的姿态补偿方法。该方法给出了雷达获取姿态数据的流程,通过将姿态数据解耦合的方式,把姿态补偿转换为分步坐标系旋转变换,得到了点迹姿态补偿和波束指向姿态补偿的处理流程。根据应用结果证明,多功能相控阵雷达通过姿态补偿,降低了方位角和俯仰角误差,提高了雷达对目标的跟踪精度。
When multifunction phased array radar is working during the march,the wobble of carrier platform attitude will make the track measurement and beam direction of the radar deviate from the real value,and there is an angle error,which is difficult to meet the radar’s requirements for tracking accuracy of target.In view of this problem,an attitude compensation method for multifunction phased array radar is proposed.This method presentes the process of radar obtaining attitude data,and by decoupling the attitude data,the attitude compensation has converted into a step-by-step coordinate system rotation transformation,and the process of attitude compensation for the track measurement and beam direction is obtained.According to the application results,multifunction phased array radar reduces the azimuth and elevation angle errors and improves tracking accuracy of target through attitude compensation.
