Abstract

Abstract

Based on a simple formula for calculating the main beam efficiency presented in Ref.[1], the main beam efficiency calculation is performed for multi-band microwave radiometer antenna boarded on "SZ-4" spaceship. The calculation shows that the main beam efficiencies at 6.6, 19.35, 23.8 and 37 GHz are 89%, 91.24%, 92.91% and 94.87%, respectively.
