Land-Sea Contamination Analysis for the Interferometric Radiometers Onboard the Chinese Ocean Salinity Satellite

The Chinese Ocean Salinity Satellite is part of the Chinese ocean dynamic satellite series, and is dedicated to global SSS observation with two payloads onboard. These two payloads, named the Interferometric Microwave Radiometer (IMR) and the Microwave Imager Combined Active and Passive (MICAP), both adopt interferometric aperture synthesis technology. To analyzes the Land-Sea Contamination (LSC), which is one of the mainly issues that degrades the salinity measurement in coastal areas for an interferometric radiometer, we perform a simulation to compare the LSC effect for the two different L-band interferometric radiometers. Results and a preliminary strategy to mitigate the LSC are presented and discussed.
