摘要
雷达导引头低空性能主要受地杂波和多路径效应的影响。本文利用雷达不可分辨双源理论重点分析了单脉冲雷达导引头在有多路径效应存在时的角跟踪性能,并通过实例建立了利用布儒斯特角效应和目标与镜像的多普勒频率差从多路径干扰中分辨真实目标的定量分析方法。
The performance of air defence missile radar seeker in low-altitude tracking is mainly effected by the ground clutter and multipath interference. The paper deals with the monopulse radar seeker angle tracking performance under the condition of multipath effect on the basis of radar theory on two unresolved sources. A quantitative approach is proposed for separating true target returns from multipath contamination by use of the Brewster angle effect and the doppler difference frequency between target and its image. Practical example is also given.
