Analysis and application of differential propagation phase shift in polarization-diversity radar measurements of precipitation at centimeter wavelengths

摘要

Discusses the relation between differential propagation phase shift Delta Phi and rainrate R, which is found to be nearly linear and be almost insensitive to the dropsize distribution parameters. The studies show that by using Delta Phi method, we can extract rainrates from CDR radar and correct propagation effects on CDR radar data. It is clear that the technique of differential propagation phase shift can be applied as a potential tool to improve measurements of precipitations in remote sensing.
