摘要
在战斗机低空突防过程中,防止敌方发现我机或使敌难以发现和跟踪我方飞机,是运用电子干扰设备压制敌警戒、引导和目标指示雷达的主要目的。首先建立了有源电子压制数学模型,研究了压制后对威胁空间的影响。然后基于突防飞机的需求建立了满足突防的压制条件。仿真表明了电子压制模型的正确性,该方法对敌方火力威胁区域的航迹规划提供了理论依据。
In low-altitude penetration, oppressive jamming is used for blinding all the enemy radars in order to prevent the adversary from or make it difficult in finding or tracking the attacking aircraft. In the paper, a method is presented for analyzing the influence of active oppressive jamming on operational effectiveness of ground-based early warning radar. Then, the oppressing conditions satisfying low-altitude penetration requirements of the attacking aircraft are built up. The effectiveness of electronic countermeasure is computed by analyzing the radar＇s efficiency under jamming and without jamming. Simulation results proved the validity of the method, which supplies a theoretical basis for trajectory planning of aircraft.
