摘要

摘要: 星载合成孔径雷达(Synthetic Aperture Radar, SAR)作为一种主动式微波成像传感器，能够不受天气、气候以及光线的影响，可以全天时、全天候地成像，因此，星载合成孔径雷达已发展成为一种不可或缺的对地观测工具。随着技术的进步，未来星载SAR将实现高分辨率宽测绘带、低成本、小型化、多基多模式微波成像，并具有地面运动目标指示的能力，在最小的成本下获得最丰富的地物信息。这迫切需要星载SAR系统在新模式、新体制、新技术方面取得重大突破。该文将围绕星载合成孔径雷达技术发展现状及未来趋势展开论述。

Abstract: Spaceborne SAR, which is a kind of initiatively microwave imaging sensor, plays an important role in gathering information with its capability of all-day and all-weather imaging, and has become an indispensable sensor for observing the earth. With the development of SAR techniques, Spaceborne SAR has been provided with the ability of High-Resolution Wide-Swath, miniaturization with low cost, bistatic and multi-mode imaging, and Ground Moving Target Indicating (GMTI), so more accurate information about the culture could be obtained with lower cost. In the meantime, more technique problems with muliti-mode, new work system and complex environment are arising and needed to be solved. The main work of this paper is discussing the current situation and the future development of Spaceborne SAR.
