摘　　要：应用Nrad修正的海面回波反射强度GIT模型和瑞利海杂波背景中的目标检测概率计算模型,给出末制导雷达目标检测概率与海浪级数、风向角以及目标RCS之间的变化关系曲线;确定了STC电路输出控制电压与海杂波干扰功率的"匹配参数"。通过蒙特卡洛法得到不同导弹自控终点散布误差和不同末制导雷达搜索选择区范围条件下的目标覆盖概率与导引头自导作用距离和箔条弹布放距离之间的变化关系曲线。通过某末制导雷达抗干扰性能仿真系统得到目标捕捉概率与自导作用距离之间的关系曲线,并就提高干扰背景中末制导雷达目标捕捉概率提出几点想法。In the beginning of this paper,according to the corrected GIT（Georgia Institute of Technology） model of reflecting quotiety of sea echo and target detection probability＇s calculational model in Rely sea clutter environment,the graphs of relationship between target detection probability of terminal guidance radar and ocean wave scale,wind direction,and target＇s RCS（Radar Cross Section） were proposed.＂Matching parameters＂ between the received sea clutter power and the control voltage output of STC（Sensitivity Time Control） circuit were ascertained.The graph of relationship between target covering probability and self-guidance range,and shoot range of dilution jamming under different scattering error of terminal point of self-control phase and different search-choosing areas of terminal guidance radar were proposed by the method of Monte Carlo.The graph of relationship between terminal guidance radar＇s capture probability and self-guidance range was given through the anti-jamming capability simulation system of a radar seeker.And,some advices about how to improve target capture probability in jamming environment were given.
