中文摘要：

为了能够迅速准确地对多部干扰机进行支援干扰时的效果做出评估，通过雷达干扰的空间能量方程，在对单部干扰机进行分析的基础上，推导出多部干扰机进行支援干扰时的压制区域模型。通过仿真绘制了压制区域图形并设计了支援干扰区域的GUI仿真界面，由此可以得到每个方位上的最小干扰距离。以最小干扰距离作为干扰效果评估准则，对不同态势下的干扰效果进行了仿真，并分析了影响支援干扰效果的各种因素，为如何对有源干扰资源进行合理布站和分配以及对定量研究支援干扰效果提供了新的方法。

英文摘要：

To evaluate the jamming effectiveness of multi-jammers quickly and accurately in stand-off jamming, the model of suppressing area under the case of multi jammers based on the analysis of single jammer is established through radar jamming space-energy formulas. The suppressing area figures are drawn through computer simulation and the GUI simulation interface of suppressing area is designed, from which the minimum jamming range used as the efficiency evaluation principle could be gained. Through the simulation on jamming effectiveness under the different operational situations, the factors of influencing stand-off jamming effectiveness are analyzed and a new method of evaluating the jamming effectiveness is supplied.
