多路径效应对雷达导引头影响

Influence of Multipath Effect on Radar Seeker

为解决雷达导引头测角出现偏差的问题,在海面多路径效应下,对舰空导弹主动雷达导引头的影响进行研究。依据多路径效应的技术原理,结合导引头与目标的几何位置关系,构建多路径效应模型,利用仿真方法,分析目标飞行高度和擦地角对雷达导引头跟踪角偏差的影响。仿真结果表明,该研究为雷达导引头降低多路径效应提供了参考依据。

To solve the problem of the radar seeker measure deviation,the influence of sea surface multipath effect on ship-air missile radar seeker is researched.From the technique principles of multipath effect,according to the position of radar seeker and target,the model of multipath effect was built,use simulation method,the influence of target flight height and grazing angle on radar seeker tracing angular deviation was analyzed.The simulation result shows the test provided a reference for radar seeker to reduce multipath effect.
