摘要
针对雷达脉压通道的目标距离在实际跟踪测量中偏差较大的问题,提出了一种基于光速和多普勒频移的雷达探测距离修正方法,并借助实际雷达检飞试验中目标的全球定位系统(GPS)数据,分析了修正前后的目标距离精度,验证了修正方法的有效性和正确性。
Aiming at the problem that the target range deviation in radar pulse compression channel of actual tracking and measurement is relatively large,this paper puts forward a correcting method of radar detection range based on the velocity of light and Doppler frequency shift,and makes use of target global positioning system（GPS）data in actual flying test of radar,analyzes the target range precision before and after the correction,validates the validity and correctness of the correcting method.
