In this paper

detailed analysis on the principle

functions and characteristics of microwave radiometer using two reference temperatures with automatic gain compensation is made

and proposes a method of correctting calibration characteristic of two reference temperatures microwave radiometer. It also concerns to develop a airborne/ground based 13 mm microwave imaging radiometer with micro-computer control of antenna scanning

real-time data collecting and processing

falsecolour imaging

man-computer dialogue

and data recording on diskette.
