Abstract

NICT developed the airborne X-band SAR system (Pi-SAR2) in 2008. It has polarimetric and interferometric functions with high spatial resolution of 0.3m. We demonstrated volcano monitoring using DEM generated by single-pass interferometry function of Pi-SAR2. In this paper we describe coherent change detection by repeat-pass interferometry function of Pi-SAR2. We improved the repeatability of flight path by introducing the guideline system and obtained high coherence image. In flight experiments we detected the footprint on the lawn in the coherence image.
