Research on Data Acquisition Based on Millimeter Wave InSAR
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∶5 000 digital surface model(DSM)results,the reliability of airborne millimeter wave InSAR data acquisition process is fully verified.
