摘要

摘要: 针对宽带雷达目标回波存在越距离单元走动的问题，该文提出一种基于联合稀疏恢复的宽带雷达动目标检测方法。该方法先在频域对回波数据进行预白化处理，抑制杂波；然后在频率-慢时间域推导出目标信号的联合行稀疏表示，并通过联合稀疏恢复算法得到目标的频域估计；最后通过逆傅里叶变换得到目标的时域估计。仿真结果验证了该方法的有效性。

Abstract: Range migration is the basic and troublesome problem in moving target detection for wideband radar. To solve this problem, a detection algorithm of moving targets based on joint-sparse recovery is proposed for wideband radar. Firstly, a prewhitening processing is performed to filter the clutter. Then, a jointly row sparse representation of the wideband signals is derived in frequency/slow-time domain，thus the detection problem is solved via joint-sparse recovery. Finally, by using the inverse Fourier transform, the estimation of the targets scenario is achieved. Numerical results are presented to demonstrate the effectiveness of the proposed algorithm.
