有源照射箔条对相控阵雷达复合干扰效应分析

箔条在与有源干扰结合使用时会比使用单一手段更有效。应用箔条可能会强迫雷达采用MTI或多普勒处理,这样可使雷达无法使用脉间频率捷变,而且箔条扩展到无模糊距离以外会使雷达无法使用脉冲重复频率参差,这两种因素为对相控阵雷达复合干扰开辟了道路。比较了复合干扰与有源和箔条分别干扰相控阵雷达后的压制比,仿真结果表明:复合干扰效果比箔条干扰效果在随距离的变化过程中至少在3倍以上。与有源干扰相比,在30 km之内复合干扰比有源干扰具有明显的优势。这为实战条件下提高飞机生存率,具有较强参考价值。

Analysis to Active Light Chaff of Phased Array Radar Compound Jamming Effect

Chaff is more effective compared with Chaff may force radar to adopt MIT or Doppler processing,which make radar can not adopt frequency agility between the pulse and for not adopt irregular pulse repetition frequency. This two complications open up a new way for PAR’s compound jamming. This paper compares the suppression rate of compound jamming active jamming and chaff jamming with PAR. The simulation results show that the effects of compound jamming are also improved than three times at least with changing of distance. Compared the active jamming,compound jamming has the obvious advantages to active jamming within 30 km. It has tremendous reference value in practical battlefield to improve the survival rate.
