However,if we use the conventional technology,once the spatial resolution reaches a certain level,the small resolution cell will limit the sensitivity of the brightness temperature measurement due to very short integration time at each of the cell.In this paper,a new technology,so called interferometric radiometry or synthetic aperture radiometry,is summarized.
