| 摘 要： | 目标运动带来的距离与速度模糊问题会使毫米波线性调频连续波近程探测雷达的测距精度大大降低。，本文提出了一种利用分数阶Fourier变换及自相关得到雷达回波信号参数，从而估计出运动目标精确距离的方法。同时，文中给出一种新的快速搜索算法，提高了计算速度，并具有较高的测距精度。与中国余数理论方法相比，该方法算法具有处理简单、计算量小等优点。仿真结果验证了该算法的有效性。

| Abstract: | The range-velocity ambiguity caused by the movement of a target has terrible influence on the ranging accuracy of a millimeter wave linear frequency modulated continuous wave short-range radar.A new method was presented to reduce the range-velocity ambiguity and improve the ranging accuracy by estimating parameters of the radar echo signal with fractional Fourier transform and self-correlation.And a new searching algorithm was given to increase computing speed and ranging accuracy.Compared to Chinese remain... |
