Abstract :
A digital multi-beam microwave radiometer is presented in this paper. The system consists of antenna array, receiving channel array, analog to digital convertor and PC. It is the multiply beamforming technique that is used to process the signal which is obtained from the scene. An error correction algorithm is used to improve image quality. Experimental result demonstrates the image ability of this system.
