摘要

With the continuous development of millimeter‐wave radar component integration technology, millimeter‐wave radar near‐field imaging technology has been improved and widely applied in security inspection, through‐wall detection and other scenarios. This paper first introduces the research background and significance of multi‐input multi‐output (MIMO) millimeter‐wave radar near‐field imaging. Secondly, it summarizes the domestic and foreign development status of millimeter‐wave radar and frequency domain imaging algorithms. Then, it introduces the imaging principle of MIMO millimeter‐wave radar and deduces the imaging algorithm process of MIMO millimeter‐ wave radar based on range migration algorithm. Finally, it summarizes the existing problems of range migration algorithm and outlooks the future development.
