The Water Vapor simulated from the Weather Research&Forecast Model (WRF-WV) has been utilized for InSAR (Interferometric Synthetic Aperture Radar) atmospheric correction in recent years, but its reliability in terms of accuracy of the water vapor itself and application in InSAR process are controversial. Therefore this paper inspected it by comparing WRF-WV with Medium Resolution Imaging Spectrometer...
The research focuses on high precision airborne SAR geometric calibration (GC) and geolocation (GL) on the condition of long flight time. The experiment was conducted in Inner Mongolia, China, and based on image pixels' GL model, calibration parameters and procedure proposed in literature [1], two systematic parameters (near range R0 and slant range resolution ρr) were calculated and validated. But,...
As a component of interferometric phase, atmospheric phase influences accuracy of millimetric land deformation measurement. Though Atmospheric Phase Screen (APS) can be estimated by Persistent Scatterer Interferometric Synthetic Aperture Radar (PS-InSAR) technology, they are pseudo without consideration of actual atmospheric state and topography. This paper researches into ineffective separation of...
Atmospheric disturbance can strongly influence the accuracy of Ground-Based synthetic aperture radar differential interferometry (GB-InSAR). In this paper, a comparison of different techniques for compensating the atmospheric artifacts in Ground-Based SAR is presented. The way the fluctuation of atmospheric parameters like temperature, pressure and humidity among successive scans affects interferometric...
