APPARATUS FOR SENSITIVITY IMPROVEMENT OF RADIOMETERS BY USING IMAGE FREQUENCY BANDS

摘要

The present invention relates to a radio meter, and more particularly, to a radio meter sensitivity enhancement device capable of further improving sensitivity even in a limited input frequency band of a detector. According to the present invention, after the image signal band is generated and used, the sensitivity can be further improved even in a situation where a usable frequency band is restricted by an antenna or the like, that is, the input frequency band of the detector is limited.
