研究了电子干扰下的舰艇编队雷达探测距离及水平杀伤区。分析了有源压制干扰、无源干扰和分布式干扰下的雷达作用距离模型,给出了受雷达作用距离限制的舰空导弹杀伤区远界计算方法,并对电子干扰下编队协同防空时的雷达重叠探测区、导弹水平杀伤区及舰艇间距进行了仿真。分析表明:干扰情况下,编队的雷达威力范围下降了约30%,不具备全向攻击能力的舰空导弹水平杀伤区范围下降了约75%;抗击亚音速飞机类目标时,编队间距宜保持在16km。

In this essay, the radar detection range and anti-air missile horizontal kill zone in fleet coordinate air defense were studied. The radar detection range model under active blanket jamming, passive jamming and distributed jamming was analyzed. The far boundary of anti-air missile kill zone calculation algorithm was also given. Then the overlapped radar detection area, horizontal kill zone in fleet coordinate air defense and spacing length of ships under jamming were simulated. Results show that when jammed, the radar detection area reduces by 30%; ship-to-air missile kill zone area reduces almost by 75%. If targets are planes with subsonic speed, the distance between formations should be 16 kilometers.
