舰艇作战系统雷达统一对准模型及其误差分析

  目的  由于保障舰载相控阵雷达电轴的静态对准较为困难，因此需开展动态对准方法研究。  方法  通过实时测量舰船姿态及位置信息、信号源位置信息，在统一时间基准下，经姿态修正、位置间隔修正算法，获得实时的目标真值及相控阵雷达探测值，得到相控阵雷达电轴零位误差，进而达到动态对准的目的。  结果  仿真结果表明，该方法的对准精度可达到0.5'左右，  结论  满足相控阵雷达对准的要求，同时降低了保障要求，节约了试验成本，具有较强的灵活性与机动性。

A unified radar alignment model with error analysis for shipboard combat system

  Objectives  Phased array radar is difficult to ensure the static alignment of electric axis, therefore a research into dynamic alignment method is conducted.  Methods  With the real-time measurement of the ship's attitude and position information and the signal source position information, the real-time target true value and detection value of the phased array radar are obtained through attitude and position correction algorithms with a unified time reference. Then, the zero error of the electric axis of the phased array radar is obtained, thus achieving dynamic alignment.  Results  The simulation results show that the accuracy of the alignment method can reach about 0.5'.  Conclusions  This method meets the alignment requirements of phased array radar, reduces the requirement and saves the test cost, and has strong flexibility and mobility.
