Wind shear is one of the most important factors causing air accidents. It can be detected by airborne forward-looking weather radar, which is key equipment for safeguarding air transportation. With great danger and short duration, the real radar data of wind shear is difficult to acquire. So the echo simulation of the wind shear is important to the research of the wind shear detection. In the paper, a new idea for simulating the echo signal of wind shear is proposed. Firstly, a high-fidelity wind shear field is produced from the wind shear model with wind field simulation software. Then it is used to generate the time series data of radar by simulating radar operation. Finally the analysis of the simulation results demonstrates that the simulation is reasonable.
