Abstract

Abstract

Microwave Imager Combined Active and Passive (MICAP) is a new ocean salinity measure. The imager is composed of L, C, and K band radiometers and an L band scattermeter. The L band one dimensional synthetic aperture radiometer is a key part of MICAP, which is used to realize the high precision measurement of the ocean salinity. In order to demonstrate the concept and performance of MICAP, a ground-based prototype is developed and experiments are carried out. This paper introduces the development and experimental results of the L band synthetic aperture radiometer in the MICAP prototype. For the first time, a method is proposed to correct the AD offset error of digital to analog correlation conversion by using the three level quantization means. These experimental studies provide technical preparation for both the future Chinese ocean salinity mission and the global water cycle observation mission.
