The mathematic model of deviation angle distribution of uniform thickness conical surface windshield glass was deduced based on the theory of ray-tracing,and a method for establishing the engineering model of angle of deviation was also proposed .Based on which,an approximate model with high-precision was developed by using least square method .The model is applicable for real-time compensation of the relative deviations for the onboard software,which has been applied in a certain type of airplane successfully .
