摘要

摘要: 该文提出了一种新的基于弧形阵列直升机载MIMO微波成像模式，利用平台下方水平布置的弧形阵列天线，通过MIMO信号收发机制快速实现弧形孔径合成，获取平台周围观测区域的高时间高空间分辨率2维图像。文章详细介绍了弧形阵列微波成像的工作原理，建立了相应的成像信号模型，研究了基于共焦投影技术的弧形阵列微波成像算法，分析了该成像模式的成像性能；最后，通过计算机仿真验证了该成像模式的可行性和有效性。

Abstract: This study proposes a novel Multiple Input Multiple Output (MIMO) microwave imaging mode based on arc antenna array, which is mounted on the belly of platform. In this mode, an arc aperture is quickly synthesized using an MIMO. Consequently, high space and time resolution images of the illuminated scene around the platform are acquired. First, an imaging principle model based on arc antenna array is described, and its signal model is developed. Then, an imaging algorithm based on confocal projection is discussed and the performance of the mode is analyzed. Finally, the feasibility of the imaging mode and the validity of the proposed algorithm are demonstrated with a numerical simulation.
