Measurement of the efficiency and scattering coefficient of millimeter-wave reflector antennas according to their thermal microwave emission
Abstract
The paper describes a recently developed and verified technique for measuring the efficiency and scattering coefficient of large and small reflector antennas according to their thermal emission in the millimeter-wave range. This technique was used to evaluate the efficiency of the RT-22 radio-telescope antenna.
