Analysis of range migration and Doppler history for an airborne passive bistatic SAR radar

Abstract

This paper presents an analysis of range migration and Doppler frequency rate-of-change for an airborne passive bistatic radar (PBR) utilizing the synthetic aperture radar (SAR) technique in the imaging of ground objects. The study was carried out for PBR using the Digital Video Broadcasting - Terrestrial (DVB-T) transmitter as an illuminator of opportunity. The results obtained have been verified using both simulated and real data gathered by a PBR mounted on an airborne platform.
