AbstractThe interferometric synthetic aperture microwave imager (IMI) on WCOM is a one-dimensional L/S/C tri-frequency microwave radiometer aiming to improve the measurement capability on soil moisture and ocean salinity. The IMI antenna is mainly consisted with the deployable parabolic cylinder mesh reflector and the tri-frequency linear patch feed array. The distribution of antenna feeds is very important to the imaging quality of microwave imager. Therefore, requirement quantitative evaluation was accomplished through proper simulation and comparing the influence of different antenna feed arrays on imaging accuracy, sensitivity and spatial resolution. This paper provides a simulation system that is consistent with the real data processing. The efficient and optimal feeds array arrangement is also selected for IMI system after simulation and evaluation of the imaging results of several different feed arrays.
