摘　　要：基于对指挥自动化系统日常积累的雷达情报数据进行处理,提出了一种改进的雷达探测概率计算方法。综合考虑了目标在飞行过程中,RCS随着其与雷达相对位置的变化而变化的因素,对各个高度层上的航迹按距离取样间隔分段,统计各分段内的观测点数和发现点数,从而计算各距离取样间隔内的发现概率,再根据目标相对雷达的俯仰角和方位角对距离取样间隔中心点的探测距离进行修正。Based on the processing of the radar intelligence data from the command automation system, an improved computation method of radar detection probability is presented. The method here takes into account the targer RCS changing with the different detection attitude. It partitions the track in various height according to the distance sampling spacing, then calculates the found point number and the unfound one in each distance sampling spacing to calculate the detection probability of each one. And then it corrects the distance sampling spacing center＇s detection distance according to azimuth and pitch of the target.
