Abstract :
Wind shear is recognized by a major hazard during takeoff and landing of aircraft, which can be detected by airborne forward-looking weather radar. A high-fidelity wind shear model constructed by the Computational Fluid Dynamics software has been implemented in this study. The model is reasonably representative of the downward wind falling to the ground during the mature phase of the microburst wind shear. The results of the radar echo signal simulation based on the above wind shear model show that the distribution of the velocities has an obvious horizontal "S" shape. The simulated results demonstrate the typical characteristic of the microburst wind shear.
