摘　　要：雷达系统误差配准是雷达组网的前提和基础,对于探测距离远的雷达,其在探测空间内的测量误差呈现明显的非均匀分布特性,导致传统的系统误差校正方法难以满足误差校正需求。针对雷达系统误差存在的非均匀分布特性,将雷达探测空间分成若干小区域,每个小区域可以认为系统误差为定值,此时,可在每个区域内利用迭代最近点算法计算该区域中的雷达系统误差,形成全探测空间内的系统误差补偿矩阵,从而实现对非均匀分布系统误差的准确校正。最后,通过实测数据实验验证了提出方法的有效性。Radar system error registration is a prerequisite and foundation for radar networking.For radars with long detection distances,their measurement errors in the detection space exhibit obvious non-uniform distribution characteristics,which causes traditional system error correction methods to be difficult to solve the error correction problem.In response to the non-uniform distribution characteristics of radar system errors,this paper proposes to divide the radar detection space into several small intervals,in each of which the system errors can be considered as a fixed value.At this time,the iterative closest point algorithm can be used to calculate the radar system error in each interval,and finally a system error compensation matrix is formed for the entire detection space,thereby achieving accurate correction of non-uniform distribution system errors.The effectiveness of the proposed method is verified by the experimental data.
