Design and performance of a spinning flat reflector for millimeter-wave radiometry

Two collocated millimeter-wave radiometers were operated at the Platteville, Colorado, site from January through March 1994. These radiometers are identical, with the exception that one radiometer uses a spinning flat reflector, white the other one uses a fixed flat reflector. The spinning reflector was designed to shed precipitation particles, thus improving the radiometer's performance during precipitating conditions.
