Abstract

Latest SAR platforms carry multiple receivers in order to increase their swath with discrete phase center (DPC) approach or digital beam forming (DBF), and / or perform along track interferometry (ATI). The main purpose of placing multiple receivers is to distinguish slight differences of the scattered echo in those receivers so that we can extract the targets’ information further. From the point of view of RFI detection, those receivers can be used for advanced detection methods. As RFI is a direct wave, the received RFI signals are the same and only receiving time can shift between the receivers depending on incidence angle.
