Development of Circularly Polarized Synthetic Aperture Radar onboard microsatellite for Earth diagnosis

Synthetic Aperture Radar (SAR) is well-known as a multi-purpose sensor that can be operated in all-weather and day-night time. Recently, many missions of SAR sensors are operated in linear polarization (HH, VV and its combination) with high power, sensitive to Faraday rotation effect etc. In this research, we proposed the Circularly Polarized Synthetic Aperture Radar onboard microsatellite (μSAT CP-SAR) that will be launched in 2014 to retrieve the physical information of Earth surface for Earth diagnosis.
