Abstract

Abstract: The fluid mechanics principle and the triangle harmonic function were used to establish a simple and high real-time typical strong wind-shear field model. The simulation data of wind field velocity in horizontal fan-shaped scanning mode and vertical scanning mode based on the parameter and detecting mode of airborne phase array weather radar was proposed. The different characteristics of strong wind shear detected by airborne weather radar on the different altitude were proposed through simulation data analysis. The simulation data credibility of strong wind shear field was analized based on weather radar velocity of a strong squall line process. The wind field model data could apply to the phase parameter simulation in the airborne radar signal processing. The analysis result of the wind field simulation data could also provide the theoretical guidance to actual flight experiment.
