This dissertation studies the wind shear field, modeling and simulation of wind shear radar echo. Firstly it introduces the concept of wind shear, classification, causes and its impact on aviation safety of flight. Then it generally introduces wind shear detection technology and signal processing methods. It finishes computer simulations and gets an echo signal velocity spectrum. Finally it develops a software for wind shear echo model simulation. The computer simulation results show that the
