PALSAR-2 on ALOS-2 developed by JAXA, is a follow-on L-band SAR sensor from PALSAR on ALOS. The mission objectives defined by JAXA include contribution to disaster monitoring. To establish the methodology to acquire the damaged area for disaster monitoring, we need to improve our understanding of the relationships between the sensor parameters (e.g., coherence and errors of the interferogram) and...
