Abstract
The Advanced Land Observing Satellite-2 (ALOS-2, “DAICHI-2”) operated by Japan Aerospace Exploration Agency (JAXA). The ALOS-2 carries the Phased Array type L-band Synthetic Aperture Radar-2 (PALSAR-2). The PALSAR-2 can observe the disaster affected area day and night in any weather with its high power and high resolution Synthetic Aperture Radar (SAR). In this paper, we report some preliminary experiments of the disaster monitoring in harbor based on Synthetic Aperture Radar Interferometry (InSAR). In order to evaluate the usefulness of the InSAR, we measured the uplift of a working model made of concrete armor units and confirmed its accuracy can be better than 2 cm in standard deviation. We also analyzed the damages in Nagata and Suma ports Kobe prefecture hit by the 11th Typhoon in 2014, and detected the damaged area with interferometric coherence analysis.
