中文摘要：
激光雷达距离高分辨多普勒成像技术具有时空域分辨率高,敏感于被识别目标的距离、姿态、运动速度等信息,可实现目标微运动检测,故该项技术已成为国外军用航天领域研究的热点。本文全面地总结了激光距离高分辨和距离多普勒成像技术研究进展,并详细分析了工程应用和理路成像仿真过程中所必须解决的关键问题,指出激光距离高分辨成像的优点和难点,为进一步开展目标激光雷达成像研究奠定预先技术支持。
英文摘要：
The Laser Range-Resolved Doppler Imaging Radar （LRRDIR）will be a research hotspot in aerospace and national defence fields,because it has higher resolving power of time-space domain, and it is more sensitive to some characteristics information such as the range, attitude and moving state on the target. These advantages of LRRDIR will be utilized to detect the micro-motion of target. The technique progress on Laser High Range-Resolved Imaging Radar （LHRR）and LRRDIR are comprehensively summarized in this paper. Some key technologies that must be solved in the course of engineering applications and theoretically model on imaging simulations are systematically analyzed and pointed out the advantages and difficult problems. The works build a research foundation for further studying LRRDIR on detecting targets.
