Abstract :
We have started development of small synthetic aperture radar (SAR) compatible to 100kg class small satellites with about 3m ground resolution and multi-polarization, aiming for constellation SAR observations. This paper describes key technologies of this development such as deployable slot array antennas, waveguide feeder with a small gap at a deployment point, and GaN HEMT X band amplifier. Also we show an integration design result of this SAR system to 100kg class bus system.
