摘　　要：组网雷达系统中,由于观测信息量的增加,对目标存在多种定位算法。很多情形下,误差配准公式是基于某一定位算法推导而来,误差配准的结果也相应的用来提高此定位算法的定位精度。定位算法的复杂程度不同导致基于此算法推导误差配准公式难度不一致,不同定位算法的定位精度也不尽相同。因此,对两种多距离定位算法的定位精度、误差配准推导难易程度进行了理论分析和仿真计算,给出了定位精度的解析表达式和仿真结果。利用表达式简单的定位算法推导基于最小二乘的误差配准公式,并将误差配准结果反馈给定位精度高的定位算法,以最大程度提高误差配准结果的应用效果,减轻计算复杂度,提高信息的利用度。In a Radar netted system, there exists various location algorithms due to enough measurements. Errors registration is based on a location algorithm, and the results are used to improve location precision. Difference of complexity between location algorithms lead different difficult for inducing errors registration formula, various performance of location precision exist in these algorithms. An idea to alleviate computation complexity and enhance the use of errors registration is proposed in this paper： choose a relative simple location algorithm to induce errors registration formula, then analyze location precision of different algorithms to decide which one will have a better performance after system errors are removed.
