Abstract :
Description of experimental facilities for measurements of attenuation and phase shift in raining water formation is presented. The experimental technique is based on multifrequency wideband measurements with synthesis of signal of spatial distribution of reflection along longitudinal axis. The multifrequency measurements and synthesis have been done in real-time. The apparatus consists of modules of scalar reflectometer of series P2 (R2). The desired information is extracted from the amplitude and position of the peak of reflection from metal plate fixed beyond the zone of water raining. Some results of experimental investigation of physical model of raining medium are presented.
