基于压缩感知理论的多普勒解模糊处理
Dianzi Yu Xinxi Xuebao/Journal of Electronics and Information Technology（2011）
Abstract
多目标的多普勒解模糊处理是低脉冲重复频率(PRF)雷达的关键技术之一,论文提出一种新的基于压缩感知(CS)理论的多普勒解模糊处理方法,利用多重PRF方式下相参处理间隔内的时域欠采样特性及多普勒频谱的稀疏特性,构造了多普勒解模糊的CS模型,采用正交匹配追踪(OMP)算法直接估计出无模糊多普勒谱的幅度响应,可实现PRF分组参差方式下对多个目标的解多普勒模糊处理,仿真结果验证了算法的有效性.
