Abstract

Abstract

Based on the theories for determining wind fields with dual-Doppler radars and the technology of Doppler radar data processing, the intrinsic factors affecting dual-Doppler retrieval reliability are analyzed. Because of the limitations of radar determination methods, there exist non-simultaneity and differences in illuminant volumes and spatial positions in measurement data from two radars. Since the microwave transmission curve is not straight and the earth surface is not flat, the retrieval of the dual-Doppler radar sounding technology is influenced seriously. When wind fields derived from dual-Doppler radar observation are used, their reliability must been analyzed.
