Flight Experiments of Airborne High-Reso lution Multi-Parameter Imaging Radar, Pi-SAR

摘要

The Polarimetric and Interferometric Synthetic Aperture Radar (Pi-SAR) is an airborne high-resolution imaging radar system, having developed and being operated by Communications Research Laboratory (CRL) and National Space Development Agency of Japan (NASDA). It-consists of an X-band synthetic aperture radar and an L-band one, both of those are fully polarimetric and the X-band one has two receiving antennas located in cross-track direction for interferometrc observation. It has been operated for research purposes since 1996, to produce high-resolution polarimetric radar images all over Japan. In this paper we summarize results of Pi-SAR observation experiments, as well as its purposes and future plans.
