随着现代电子战的快速发展，机载自卫有源干扰成为了对抗雷达最有效措施之一，严重威胁雷达探测效能与生存能力。从作战效能评估需求出发，选取探测概率作为定量评估指标。首先把雷达探测过程分解成不同功能模块，通过各模块的有机结合构建探测模型，并详细介绍了各模块数学模型。然后，对雷达动态探测过程进行功能仿真，并基于HLA平台开发仿真系统。最后，通过仿真，能在线获得对应目标距离的探测概率，并以此定量分析了有源自卫干扰下雷达探测效能。仿真结果验证了模型和方法的可行性与有效性，对雷达反对抗研究提供一定的参考依据。

Simulation of Radar Detection Effectiveness Under Airborne Active Self-Defence Jamming

The airborne active self-protect jamming becomes one of the most effective defense measures with the rapid development of EW (Electronic Warfare). The detection effectiveness and survivability of radars in the battle is seriously threatened. According to the demands for assessing the detection effectiveness of radar, detection probability is selected as a quantitative evaluation index. Firstly, via the organic combination of different modules resolved from the detection process of radar, the detection model is established and the mathematical models are recommended in detail. Then functional simulation of the radar detection process is devised, and the system based on HLA is realized. Lastly, detection probability with its target distance is obtained online through the simulation, and it is used for assessing the detection effectiveness of radar quantitatively. The result indicates that this model and method is feasible and effective, and it could provide some reference material for the research to radar counter-counter measures.
