A Down-looking 3D Imaging Radar Based on Sparse MIMO Linear Array

给出了一种基于稀疏MIMO线阵的毫米波下视三维成像雷达系统设计方案,包括硬件设计、控制策略、软件设计等。针对所提方案,进行了系统级算法仿真。仿真结果表明,所提方案可实现下视三维成像,在200 m高度处三维成像分辨率可达到1 m(跨航向)×1 m(方位向)×1.2 m(高度向)。

A system design scheme of a down-looking 3 D imaging radar based on sparse MIMO linear array is presented,including hardware design, control strategy, software design and so on. Some system level simulations are carried out to verify the presented design scheme. Results show that at the height of 200 meters, 3 D resolution of the imaging radar can be 1 m(cross-track)×1 m(along-track)×1.2 m(height).
