Polarization-Diversity Radar and Lidar Technology in Meteorological Research. A Review of Theory and Measurements,
Abstract
Research in polarization-diversity radar and lidar technology as applied to meteorology is reviewed. Review of theory includes development of models for computing hydrometeor backscatter in main and orthogonal channels and development of techniques for interpreting measured parameters. Measurement programs have generally been undertaken with a particular operational objective, such as the identification of hail in severe storms or the measurement of propagation effects. Such programs have generally involved either backscatter measurements or point-to-point propagation measurements. Recent developments have shown that propagation parameters can also be derived from backscatter measurements. The current status of several applications of this technology is described. These include identification of the thermodynamic phase and shape of hydrometeors, the detection of hail, the direct radar measurement of rainfall rate, and the use of polarization diversity for coding of Doppler radar pulses.
