摘　　要：针对雷达组网系统探测精度的考核问题,提出了一种评估雷达组网系统探测精度的方法。基于最大似然估计法、最小二乘估计法及加权最小二乘估计法,推导了衡量雷达组网系统探测精度的3种分析评估方法。通过性能对比,选择性能最优的最大似然估计评估法运用到某雷达群组网探测系统实际检飞考核试验中,获得了较好的评定结果。Aiming at the difficult detection precision test problem for a netted radar system, a method of calculating detection precision for netted radar system is proposed in this paper. Three detection precision estimation methods are deduced which are based on maximum likelihood estimation （MLE）, least squares estimation （LSE） and weighted least square estimation （WLSE）. Through the performance comparison, combined with actual data , MLE was chosen to the flight test of a certain netted radar system, and the evaluation result is satisfactory.
