Abstract : Facilities for determining the orthogonal components of the angle scattered signal and the backscattered signal of reflections from hydrometers for a vertically looking radar operating an X-band were developed. Meteorological instruments such as tipping bucket rain gages, anemometer, thermometer, and drop size distribution counter were employed for surface control. Measurements were made on a number of rain showers and were analyzed. Excellent agreement was found between the amplitude of the bistatic radar signals, both E subscript theta and E subscript phi, and the rain rate determined by the tipping bucket rain gages. The drop size distribution meter indicated distribution functions that were in close agreement with a two parameter distribution proposed by Marshall-Palmer. (Author)
