High-compacted FM-CW SAR for boarding on small UAVs

In this paper a compact, lightweight, low power consumption airborne SAR sensor able to be fitted in an UAV is presented. The Air-Based Remote Sensing (ARBRES) system is based on the previous experience acquired in developing GB-SAR sensors for subsidence and landslide monitoring. Prior to the in-flight evaluation of the developed SAR, different tests were performed boarding the hardware on a car to evaluate its performance. After this debugging step, tests of the system in an airborne platform were carried out and the results are presented. GPS and INS systems are used to record the aircraft position, velocity, and attitude for future Motion Compensation (MoCo) Techniques.
