| 摘 要： | 轴系误差是影响潜望式光电仪器测角精度的重要因素,传统轴系误差模型使用大量数学近似,存在适用局限性。将轴系误差的产生用坐标变换的方法来表现,建立了一种精确的数学模型。推导了高度角误差与方位角误差的微分计算方法,在MATLAB上进行了仿真计算,验证了模型的正确性。该模型综合考虑了各种误差的影响,不存在数学近似引起的原理误差,为潜望式光电仪器的轴系误差补偿校正提供了参考。

| Abstract: | Shafting error is an important vector in angle measuring. There is a lot of approximating in the old shafting error model which is only fit for very small errors. A mathematic model of shafting error is founded by a coordinate transformation method, which works out the coordinates of the aim vector. The calculation of the altitude error and azimuth error is deduced by differentiation. Using Matlab to calculate the shafting error which proved the error model. Provide reference for shafting error correction. |
