摘要
机载毫米波干涉合成孔径雷达(InSAR)穿透雾、烟、灰尘、云、雨的能力强,具有全天候、全天时的特点,在复杂区域从事测绘工作的优势明显。但在数据获取过程中,需要研究如何规范流程才能获取高质量的数据。文章阐述了毫米波InSAR测绘的基本原理,重点介绍了数据获取的流程,并在试验案例中得以应用,通过所生产的1∶5000的数字表面模型(DSM)成果,充分验证了机载毫米波InSAR数据获取流程的可靠性。
Airborne millimeter wave Interferometric Synthetic Aperture Radar(InSAR)has strong ability to penetrate fog,smoke,dust,cloud and rain.It has the characteristics of all-weather and all-time,and has obvious advantages in surveying and mapping work in complex areas.However,in the process of data acquisition,it is necessary to study how to standardize the process to obtain high-quality data.This paper expounds the basic principles of millimeter wave InSAR surveying and mapping,focuses on the process of data acquisition,and applies it in the test case.Through the production of 1∶5000 digital surface model(DSM)results,the reliability of airborne millimeter wave InSAR data acquisition process is fully verified.
