Abstract

On basis of developing the synchronous detection Dicke radiometer, a 3mm radiometric imaging system that is controlled by PC and MCU is presented in this paper. Also, the master-slave hardware and software design of imaging system is proposed for the ground application. The beam width of 3mm radiometer is 0.5degree, which makes the imaging system possess higher spatial resolution. The experimental results show that the imaging system works stably and flexible but the radiometer need depressing the affection of system noise for further step.
