The present invention relates to a radiometer and, more particularly, to a radiometer sensitivity increasing apparatus capable of additionally increasing sensitivity in a situation in which an input frequency band of a detector is restricted. According to the present invention, an image signal band is generated and then is used, thereby additionally increasing the sensitivity in a situation, in which a usable frequency band is restricted by an antenna and the like, that is the situation in which the input frequency band of the detector is restricted. The radiometer sensitivity increasing apparatus includes an antenna, a load with a preset frequency different from a frequency of a reception signal, a first switch for generating an output signal, a first radiometer path for generating a first pulse signal, a second radiometer path for generating a second pulse signal, and a second switch for generating a final output signal.
