INVESTIGATION OF DISPLACEMENT MEASUREMENTS PERFORMED WITH A GROUND-BASED FIXED RECEIVER BISTATIC SAR SIMULATOR

Ground-based fixed receiver bistatic synthetic aperture radar (SAR) is a technology increasingly used in urban monitoring, complementing and enriching the traditional monostatic SAR, but the acquisition geometry is more complex than in the monostatic case. Hence, in the design and configuration of real bistatic SAR systems simulations are needed. In this regard we have presented in [1] a simulator for this geometry that could be used as a way to explore the possibilities given by this configuration. One of the many SAR applications that could be transposed to the bistatic case is displacement measurement. It can be used in urban and non-urban environments, as a way of monitoring the change in the position of some objects of interest, like dams and buildings, using the interferometric phase obtained from two or more SAR acquisitions. This paper aims to investigate by simulation displacement measurements in ground-based fixed receiver bistatic geometry.
