| 摘 要： | 研究了飞机与雷达探测系统遭遇时，雷达对飞机的探测概率随距离的变化问题，采用X^2类目标波动模型，针对飞机在有源干扰保护的情况对探测概率随距离的变化进行了研究，对不同RCS对探测概率的影响问题进行了分析，研究结果可为飞机的雷达探测敏感性评估，飞机生存力的定量化分析与权衡，以及雷达探测系统的效能评估提供量化依据。

| Abstract: | The first encountered threat against aircraft during the mission flight is a hostile detection system. The variation research of detection probability versus range is the foundation for the high level analysis and evaluation of aircraft detection system engagement. This paper develops a new way to handle this problem and also presents the calculation processes. Based on application samples, we analyze the influences of various radar cross sections (RCS) and jamming to the detection probability of aircraft. The sample results show the feasibility and validity of those methods and processes. |
