| 摘 要： | 在最小二乘ECEF法雷达系统误差配准的基础上,给出了广义最小二乘ECEF法的计算过程.结合实际使用时长期公共目标选择的难题,提出了多目标GLS法来估计雷达的系统误差,能充分利用监视空域内的短期公共目标.通过仿真,验证了多目标GLS法在减少计算量的同时,能保证算法的有效性.利用目标优选和数据融合的方法构造的合作校准法,把组网雷达两两配准的结果进行融合,进一步提高了估计精度.仿真结果显示,在提高径向误差估计精度的同时,合作校准法能大幅度提高角度误差估计的精度.

| Abstract: | Based on least square ECEF method for registration of radar system error,the procedure of general least square(GLS) ECEF method is introduced.To encounter the difficulty in selection of long-time-tracing public target,this GLS method is extended to multi-targets field,which can fully use short-time-tracing public targets in surveillance space.Through simulation,the multi-target GLS method can not only reduce calculation time,but also guarantee the effectiveness of estimation.The cooperative method,which use... |
