Low-cost microwave radiometers can be built using a low-noise downconverter for satellite TV reception and a software-defined radio. Errors due to system gain and noise temperature drift can be corrected using motorized black body and noise injection. Successful solar observations have been made with such a radiometer mounted on a 75 cm offset parabolic dish. A joint educational project between the University of Perugia and the Technical University of Berlin is launched on this topic to give students the opportunity to practice with microwave systems, antennas, electronics and data processing.

摘要

Low-cost microwave radiometers can be built using a low-noise downconverter for satellite TV reception and a software-defined radio. Errors due to system gain and noise temperature drift can be corrected using motorized black body and noise injection. Successful solar observations have been made with such a radiometer mounted on a 75 cm offset parabolic dish. A joint educational project between the University of Perugia and the Technical University of Berlin is launched on this topic to give students the opportunity to practice with microwave systems, antennas, electronics and data processing.
