とを備えた事を特徴とするマイクロ波放射計。 A main reflecting mirror of a Cassegrain antenna, a mirror surface A that provides an antenna pattern with strong directivity when combined with the main reflecting mirror, and a mirror surface A that has a side lobe pattern similar to the side lobe pattern of the above antenna pattern, and A sub-reflector having two mirror surfaces of mirror surface B that provides an antenna pattern with a null pattern in the main beam width portion, a sub-reflector drive mechanism that alternately rotates the front and back surfaces of the sub-reflector, and a drive mechanism. A microwave radiometer characterized by comprising: a drive mechanism control unit that controls the auxiliary reflector; and a signal processing unit that processes data obtained using both sides of a sub-reflector.
