| 摘 要： | 针对超近程雷达的高速目标探测问题,提出了一种距离速度解耦合与运动补偿的新方法。通过采用单载频与线性调频连续波(CW+LFMCW)信号组合形式,由CW差拍信号测量目标的无模糊速度,再根据速度估计值对LFMCW差拍信号进行运动补偿得到目标的距离信息,实现了高速目标距离速度解耦合与运动补偿。仿真结果验证了该方法的有效性。

| Abstract: | A new method is proposed to solve the problem of range-velocity decoupling and motion compensation for high-speed target detection of Ultra-short-range Radar.The transmitted signal is a hybrid signal composed of Continuous Wave and Linear Frequency Modulation Continuous Wave (CW and LFMCW).First,the unambiguous velocity of a high-speed target is measured by CW beat signal.Then the velocity information is used to compensate LFMCW beat signal.And the range information of the target can be easily extracted from the compensated signal.The method realizes range-velocity decoupling and motion compensation of high-speed target detection.The effectiveness of the method is demonstrated by simulations. |
