Abstract： Temperature control is a simple and effective way to improve the system stability of the totalpower-type microwave radiometer,the full-polarimetric microwave radiometer can achieve high precision measurement for retrieving the sea surface wind vector by the method.Using a 23.8GHz digital-correlation full-polarimetric microwave radiometer,considering the effects of temperature on calibration of the polarimeter and adopting a special temperature control scheme,a constant temperature control system was designed to make the radiometer work stably.The experimental results show that the constant temperature control scheme can make the radiometer work in a stable state which can simplify the calibration process, make the calibration cycle longer and ensure the accuracy requirement of the calibration.
