摘　　要：用光路追迹法建立了等厚度圆锥面风挡玻璃偏向角分布的数学模型,提出偏向角工程化模型的建立方法,在此基础上利用最小二乘法得出高精度近似模型。该近似模型适用于机载软件对相关偏差的实时补偿处理,已经在某型飞机上成功应用。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.
