| 摘 要： | 合成孔径雷达(SAR)凭借其全天候、全天时的优势,在震后灾情信息的快速获取以及灾情评估上发挥着越来越重要的作用。本文分析了建筑物在SAR影像上的成像特征及不同震害等级的建筑物在SAR影像上的特点,总结了利用SAR技术进行建筑物震害检测的方法,并将其归纳为目视解译、震前震后变化检测、震后单幅影像的震害检测方法。同时分析了这些方法的特点,并对SAR建筑物震害检测方法进行了展望。

| Abstract: | With its advantages, synthetic Aperture Radar plays an increasing importance role in the application of damage acquirement and assessment after an earthquake. Firstly, the characteristic of buildings classified into different damage level on SAR image is analyzed. Then a summary of the methodology of building damage detection is discussed, which including visual interpretation, change detection using before and after image and damage detection technic using post-event image only. Ultimately, a future expectation is addressed. |
