Inertial stabilization system for small airborne SAR

An inertial stabilization system for small airborne synthetic aperture radar (SAR), which consists of an active damping mechanism and a two-axis gimbal, has been developed. Both high-frequency vibration isolation by the active damping and high stability of antenna direction under low-frequency angular disturbance have been successfully demonstrated. Also, a small airborne SAR prototype for disaster monitoring has been produced and prepared for flight tests.
