随着InSAR技术的飞速发展,大气影响对其应用的限制越发明显。近些年,国内外对InSAR大气改正的方法进行了大量的研究。本文在分析InSAR测量中的大气影响及其误差的基础上,对当前利用GPS、MODIS、MERIS、FY等外部数据,进行InSAR大气改正的主要方法进行了详细介绍,并对几种方法进行了综合比较和评价,分析了每种方法的优势和不足,最后对今后进一步研究的多星协同的综合大气改正方法进行了展望。

【Abstract】 With the development of InSAR technology,its application is significantly limited by the atmosphere effects.Great efforts have been made in recent years to develop the methods for mitigating the atmosphere effects at home and abroad.Based on the analysis of atmospheric effects and errors in InSAR measurements,this paper introduces the major methods of atmosphere correction using exterior data,such as GPS、MODIS、MERIS、FY and so on.Then analyzes the advantages and disadvantages of each method by co... 更多
