摘要
总结了激光雷达相干成像技术研究现状和进展,根据激光相干成像一般原理,针对2种最新激光雷达即距离高分辨多普勒和合成孔径相干成像技术,给出其系统技术框架和成像效果。分析了激光雷达相干成像特点及系统设计所必须解决的技术难点,指出解决问题的方案和注意问题,为我国进一步开展空间、空中和地基平台激光雷达相干成像试验研究和理论仿真奠定预先技术支持。
The technical progress and present situations on Laser Coherent Imaging Radar（LCIR）were summarized. Technical frame structure and imaging results of two kinds of typical novel LCIR such as the Laser Range-Resolved Doppler Imaging radar （LRRDI）and Synthetic Aperture Laser radar （SAL） were discussed according to the general principle of LCIR. Some key technologies Should be solved in the course of engineering applications and laser coherent imaging were analyzed. The methods to solve the problems were put forward. The purpose was to provide reference studying LCIR on detecting targets for ground base, space and air borne.
