Passive DVB- TSAR Phenomenology: First Results from a Bistatic Campaign

This paper presents progress made on the development and execution of an airborne measurement campaign to investigate the characteristics of synthetic aperture imagery from a passive system utilising DVB-T illuminator of opportunity at varying bistatic angles. A passive DVB- T receiver system was developed and flown around a target scene. A dataset of SAR images was produced with varying bistatic angles. This paper presents the first results and shows a visual investigation of image features. A point-like target within the image scene was identified in order to compare echo intensities at varying bistatic angles.

I. Introduction

Earth surface imaging via Synthetic Aperture Radar (SAR) is a popular and well-established technology for a wide range of applications and from a variety of moving platforms, such as aircraft, satellites, unmanned aerial vehicles, and ground -based vehicles.
