成果介绍

本发明公开了一种基于压缩感知的随机脉冲多普勒雷达角度‑多普勒成像的方法，包括下述步骤：S1：基于雷达体制，获得空时压缩采样数据；S2：对所述空时压缩采样数据中的多普勒频率空间和空间频率分别进行空间离散化处理，并获得空时导向词典；S3：根据所述空时导向词典估计空时功率谱，并获得包含杂波与目标的角度‑多普勒像。本发明有效解决了目标、杂波多普勒模糊问题，提高杂波抑制与目标检测性能；降低了雷达系统发射的脉冲数量，能在相同的脉冲相干处理间隔内发射其它雷达波形或者同时观测多个角度，从而有效地提高了雷达时间维的复用能力；在相同的脉冲数量下，能有效提高多普勒分辨能力；雷达波形的低截获能力，抗干扰能力更强。
