摘要
为了得到超低空背景下目标特性参数对脉冲雷达导引头目标检测的影响,根据导引头和目标的空间几何关系,推到了波程差、多普勒频移、相位差的表达式,并结合比例导引法建立多径效应仿真模型。针对目标飞行参数进行了具体的仿真并结合仿真结果对参数的影响效果进行了分析,为导引头末制导段的弹道规划与有效地规避多径效应提供参考依据。
In order to get the target parameters＇ effects on the target detection of the pulse radar seeker under the conditions of low-altitude,the expression of the distance difference and the Doppler frequence difference and the phasic difference is derived according to the geometry relationship between the radar seeker and the target,and simulation of the multipath effect model is built up combining the proportion guide methed.Aiming at the target flight parameter,the simulation result is received and the effect to the parameter is analyzed,which provide reference for the missile trajectory programming and evading multipath effect availably.
