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. Millimeter-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.
