AN/FPS-115相控阵雷达抗干扰能力分析

Analysis on Anti-jamming Ability of AN/FPS-115 Phased-array Radar

对AN/FPS-115型远程相控阵雷达,运用目前最常用的系统效能分析模型对其进行效能参数计算,得出该型号雷达系统效能值。将脉冲压缩雷达与常规雷达的增益系数进行对比,对该型号雷达的干扰压制系数与增益系数的大小关系进行研究,再利用该型号雷达的参数代入雷达干扰方程对此雷达的抗干扰能力进行分析,得出了该型号雷达抗干扰能力和对其实施有效干扰所需要的功率,购买这种价格昂贵的雷达系统对于反制导弹是无效的。

To the AN/FPS-115 long-distance phased-array radar, the author carries on the computation of effectiveness parameters using the most commonly used system effectiveness analysis model at present, gains its system effectiveness value. Comparing the gain coefficient of impulse compressing radar with the general radar＇s, the author studies the relation of disturbance suppression coefficients and gain coefficients of this kind of radar, again carries on the analysis on the anti-jamming ability with radar jamming equation using the parameters of this kind of radar and carries on its antagonization ability and the power which is used to executive effective jamming, then the conclusion that it is ineffective to purchase this kind of expensive radar system for anti-missile is obtained.
