FIRST STEPS TOWARDS SINGLE-PASS INTERFEROMETRY BASED ON A BISTATIC FIXED RECEIVER SAR SYSTEM

Bistatic radar systems will play a great role in the coming decade since a large number of radar missions are being foreseen. Using existing transmitters, formations of small passive receivers will enhance our capability to gather backscatter information from earth. A bistatic SAR system operates with separated transmitting and receiving antenna and both can follow independent trajectories. If the receiver remains stationary at certain height – on the top of a high tower for example – with its antenna pointing to the illuminated scene and a sensor of opportunity is used, we deal with a Parasitic Bistatic Fixed Receiver SAR system. In this paper we will present our prototype and the first bistatic fixed receiver results available.
