Abstract

This paper describes the reflector antenna system for the high altitude MMIC sounding radiometer (HAMSR) on a remotely piloted aircraft. The goal of HAMSR project is to design, build, and demonstrate in the field, a miniaturized microwave atmospheric sounder implemented with MMIC receiver modules and other solid state components. This passive microwave radiometer operating at millimeter wavelengths will make temperature soundings at oxygen emission lines at 53 and 118 GHz, and humidity sounding at water vapor emission line at 183 GHz. We outline the design process and the analytic results for the three feed/reflector systems at these three frequencies
