| 摘 要： | SBAS监测技术作为微波遥感技术，通过最小二乘或奇异值分解的方法，对多个构成三角网的干涉对进行干涉处理，从而得到某个地区的时间序列形变规律。本文使用SBAS技术对覆盖临沧市2019年2月—2020年7月的30景Sentinel-1A雷达数据进行处理。通过剖面和时间序列分析方法对该区域进行分析，研究其地表沉降成因和规律，以此判断该地区是否存在地质灾害的隐患区域，为临沧市以后的防灾减灾工作提供参考意见。

| Abstract: | As a microwave remote sensing technology, SBAS monitoring technology uses least squares or singular value decomposition methods to interfere with multiple interfering pairs forming a triangulation network to obtain the time series deformation law of a certain area. This paper uses SBAS technology to process the 30 Sentinel-1A radar data covering Lincang city from February 2019 to July 2020. This area is analyzed by means of profile and time series analysis to study the causes and laws of its surface subsidence, so as to judge whether there are hidden danger areas of geological disasters in this area, and provide reference opinions for the future disaster prevention and mitigation work of Lincang city. |
