Abstract

合成孔径雷达(SAR)系统在对地观测中具有全天时全天候的独特优势。近十几年来, 多模式、多角度、多维度、大幅宽、高分辨率、多基协同等SAR技术的问世, 代表着新型SAR观测时代的到来。为对这一SAR发展阶段的特点和能力进行分析, 本文首先介绍了新型SAR系统观测能力的发展, 包括如何获取大范围、多时相、多层次SAR综合对地观测数据及实现月基SAR等观测技术; 然后, 总结了杂交介质建模、时频分解、深度学习、压缩感知等新型信息提取方法在SAR领域发挥的作用; 最后, 介绍了新型SAR在城市管理、植被调查、极地与海洋测绘以及灾害监测等领域的研究进展, 旨在推动SAR观测技术在测绘领域更广泛而深入的应用。

Synthetic aperture radar (SAR) systems have the unique advantage of all-time and all-weather observation. In the past decade or so, with the continuous announcement of multi-mode, multi-angle, multi-dimension, wide-swath, high-resolution, and multi-static SAR observation technologies, SAR observation has been in the "new generation" stage. This paper first introduces the development of the observation capability of the new generation SAR, including how to realize the wide-swath, multi-temporal, and multi-level observation as well as moon-base observation; Then, the development and application of new information extraction methods such as the non-stationary statistical modeling, time-frequency decomposition, deep learning, and compressed sensing for new generation SAR images are summarized; Finally, recent application progress in urban management, vegetation mapping, polar region and ocean survey, and disaster monitoring are listed to promote wider and deeper applications of the new generation SAR.
