| 摘 要： | 一般的雷达线性调频 (LFM)脉冲波形存在多普勒频率与测量距离之间的耦合 ,即当测量的目标存在多普勒频率时 ,雷达测量目标的距离与目标所在的真实距离也存在一定的差异 ,这也可以用信号的模糊函数加以说明。提出了解决这一问题的三种基本方法和一种新的脉冲压缩波形 ,利用这种波形可以消除多普勒频率对距离测量的影响。

| Abstract: | The methods of range measurement correction which results in target Doppler frequency are presented in this paper. The targets are moving, accordingly the Doppler frequency exists. The measurement range of the LFM radars, due to Doppler frequency, is somewhat different from the actual range. In this paper the methods of range correction are put forward. The results show that the methods are effective and feasible. |
