基于多电子压制式干扰源和预警机雷达电子对抗机理,采用建模仿真的方法研究了多电子压制式干扰源作用下预警机雷达对海上目标的协同探测能力。首先分析了信干比对预警机雷达探测概率的影响,根据多点干扰源对预警机雷达的空间干扰原理,进而建立了多干扰源对多预警机雷达的干扰功率模型,得到了预警机对海上目标的探测概率计算方法。仿真结果显示了多干扰源电子压制式干扰的作用规律,验证了模型的有效性。

According to working principles of multi interference sources and detection process of AWACS radar,methods of modeling and simulation were adopted to research synthetic detection ability of AWACS radar with interference of electronic barrage jamming. Interference of SIR to detection probability of AWACS radar was analyzed firstly.Furthermore,jamming power model of interference sources was built,and calculation method of detection probability of AWACS radar was deduced. The simulation results showed effective laws of multiple interference sources,and verified effectiveness of related models.
