针对海上靶场舰载测量雷达实时姿态测量困难,雷达天线中心点实时坐标难以精确测量的问题,综合考虑靶场现有的试验保障能力、装备布设及参试情况,提出了一种基于多GPS天线的载体姿态实时测量和测量点位实时修正与雷达零位误差动态修正相结合的雷达测量信息修正方法。给出了详细的雷达测量信息修正方法、修正模型及修正流程,并对修正误差进行了分析。实际应用及测试结果表明,提出的方法能够以较低的成本实现高精度的雷达天线中心坐标实时测量及雷达测量信息姿态修正,有效解决了舰载测量雷达实时姿态测量和部位修正问题。
In view of the difficulty of real-time attitude measurement of shipborne surveying radar at sea range and the difficulty of accurately measuring the real-time coordinates of the radar antenna center point, a new multi-GPS antenna based on multi-GPS antenna is proposed based on the existing test assurance capability, equipment layout and test conditions. Real - time Measurement of Attitude of Attitude and Correction of Radar Measurement Information Based on Real - time Correction of Measurement Point and Dynamic Correction of Zero Error of Radar. A detailed correction method of radar measurement information, a correction model and a correction procedure are given, and the correction error is analyzed. The practical application and test results show that the proposed method can realize real-time measurement of radar antenna center coordinates and correction of radar measurement information with low cost, and effectively solve the problem of real-time attitude measurement and part correction of shipborne measurement radar.
