摘　　要：分析了毫米波SAR高分辨成像的基本原理,阐述了毫米波SAR的优点,并结合目前国际上典型的毫米波SAR系统,综述了毫米波SAR技术与系统的发展状况,讨论了毫米波SAR的应用前景、存在的问题以及未来的发展趋势.Synthetic aperture radar（ SAR） is a microwave remote sensing radar with capability of all-day and all-weather imaging. M illimeter-wave SAR has become important for development of SAR with the advantage of small volume,light weight,and high resolution. The basic principle for high resolution imaging of millimeter-wave SAR is analyzed,and the advantage of millimeter-wave SAR is present. The state-of-art in the development of millimeter-wave SAR technologies and systems are illustrated with some typical millimeter-wave SAR systems. The application prospects,some issues,and future development trend of millimeter-wave SAR are also discussed.
