Drop Oscillation Estimate with Multi-polarization Radar

Abstract

This paper considers the possibility of the radar polarimetry to estimate the impact of drop oscillation onto the reflected radar signal to improve information about drop shape parameters. The mathematical modeling, as well as computer simulation performed in the presented paper, demonstrate and prove the fact that it is possible to fix the contribution of drop oscillation and shape deformation into the received signal by selection of polarization angle of the receiving antenna. The results of the study can be used to improve information on rainfall or water liquid content measurements.
