Abstract

The work is dedicated to analysis of influence of the phase errors in Noise Waveform SAR on the precision of the measurements made with the help of the differential SAR interferometry (d-InSAR) method. The motivation of the research is analysis of applications of d-InSAR in monitoring of engineer constructions state with the help of ground based SAR systems. The aim of the current work is to provide analysis of the phase errors in differential SAR interferometry caused by antenna distortions. And to develop a model for estimation of their influence on the interferograms obtained. We give analytical model of the processes taking part when antenna path is distorted, analyze mechanisms of phase errors occurring and give some examples obtained using modeling of NW SAR operation. The results included in the work are used in SAR Tx/Rx unit and scanning antenna design and for analyzing obtained interferograms.
