Abstract :
An interferometric radiometer prototype at 1.4 GHz was successfully demonstrated. The system was developed for the image validation of MIRAS (Microwave Imaging Radiometer with Aperture Synthesis). The instrument, image processing procedure, and measurement results are presented. The future development of the system is discussed.
