测量雷达的距离多普勒耦合修正方法研究

Research on range Doppler Coupling Correction method for measuring Radar

线性调频脉冲压缩体制去对雷达进行测量,在对于运动目标给予精准探测的过程中,因为其受到了距离-多普勒耦合效应带来的影响,多普勒频移会令雷达出现测距上的误差,并且这一误差和目标自身的径向速度之间是一种正比的关系。对于出现的这种问题,本文在对多普勒频移对于线性调频脉压产生影响进行分析的基础上,得出了距离多普勒耦合准确的修正方式,同时使用雷达去对数据实测给予了有效的验证,其自身很好的对于测量雷达自身的测距精度给予了保证。

Linear FM pulse compression system to measure the radar for moving target in the process of giving accurate detection,because of its impact by range Doppler coupling effect,Doppler shift will appear on the radar ranging error,and the radial velocity between the error and the target itself is a relationship a proportional.For this problem,based on the LFM pulse compression effect analysis of Doppler frequency shift,the distance correction mode of Doppler coupling accurately,while using radar to give effective verification of measured data,its good for measuring radar The range accuracy of the body is guaranteed.
