Abstract :
Repeat-pass interferometric SAR (INSAR) is considered an excellent tool to detect very slight Earth crustal movement caused by an earthquake, a volcano activity, and so on. The authors developed an airborne repeat-pass INSAR system which can make very precise repeat-pass flights for interferometry. A method has been devised for getting the highly precise antenna motion using the phases from corner reflectors. In this paper, an outline of their airborne repeat-pass INSAR system, the method of measuring the precise antenna motion data and the first results in a test flight to verify the possibility of airborne repeat-pass INSAR are described
