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。
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 Con- tinuous 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 LFM- CW 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.
