摘要
分析了多径干扰经典“四路径”模型,对于弹载雷达常用波段,仿真分析了海面粗糙度、雷达波束擦地角对海面反射系数的影响,提出通过控制末制导雷达开机波束擦地角降低多径效应对雷达导引头影响,提高空空导弹低空拦截命中率的使用建议。
The classic“four-path”model of multipath interference was analyzed.For the common bands of bomb-borne radar,the influence of sea surface roughness,radar beam and the angle of grazing on the reflection coefficient of the sea surface was analyzed.It was proposed to reduce the impact of the multipath effect on the radar seeker by controlling the angle of the ground beam of the terminal guidance radar in order to improve the hit rate of low-altitude air-to-air missile interception.
