摘　　要：针对现有的雷达方位系统误差校正方法使用条件有限、精度有限等问题,提出一种基于合作目标定位数据的雷达方位系统误差在线监测估计的方法.该方法利用二次雷达能够识别合作目标且机载导航系统能够提供高精度的定位信息的原理,对地面雷达进行方位系统误差的实时监测和在线估计,以保证雷达情报的连续性和准确性.实验结果表明,该方法能够在雷达工作过程中检测并快速估计出雷达方位系统误差,具有很好的实用价值.Considering that the using conditions and accuracy of the current method for system error correction of radar azimuth are limited, this paper proposes a method for on-line monitoring and estimating the radar’s azimuth system error based on position data of cooperative targets. The real time monitoring and on-line estimating the ground radar’s azimuth system error can be fulfilled by employing the principle that the secondary radar can identify the cooperative targets and airborne navigational system can provide the position data with high accuracy, which guarantees the continuity and accuracy of radar intelligence. Experimental results show that this method can be of better practical unity for testing and fast estimating the radar’s azimuth system error while radar’s operation.
