摘要：
In this paper, a simulation method of airborne dual-polarized weather radar precipitation particle echo based is proposed. This method is based on T-Matrix method and Weather Research and Forecasting (WRF). Firstly, WRF model is used to simulate a weather scenario. Secondly, considering that the precipitation particles are spherical, the T-matrix method and microphysical properties are combined to calculate the reflectance factors of six precipitation particles. Finally, six kinds of precipitation particle echo signals are obtained by using radar meteorological equation, and the simulation of precipitation particle echo signal of Airborne polarized weather radar is realized. The simulation results show that the results can accurately reflect the meteorological characteristics, and the comparative analysis with the measured data confirms further the effectiveness and reliability of the proposed method.
