Study of HUD Operating Mode Simulation Based on the Model of the Correction Angle

研究了在某型平显仿真训练器中实现平显工作状态仿真的方法。首先介绍了平显工作画面,分析了瞄准环及其构成修正角的原理;然后通过对工作式和各相关参数的计算,建立了平显的瞄准环及其修正角的模型,并给出了计算瞄准环环心位置和直径的基本关系式;最后讨论了用VisualC++编程实现平显工作画面中公共符号和瞄准环仿真的方法。通过建立修正角模型,可使实现的平显仿真工作画面在外观上和操作特性上与实际平显工作状态一致。

This paper studies a simulation method of HUD operating mode in a certain HUD training simulator.Firstly,the working menu of the HUD is introduced and the forming principles of the aiming reticle and correction angles are analyzed.Next,the models of the aiming reticle and the correction angles are given through the calculating of the operating formulas and interrelated parameters and the basal formulas to calculate the center and radii of the aiming reticle are given.Finally,the simulation method of public symbol and the aiming reticle in the HUD based on Visual C++ is discussed.The emulational working menu is in accord with the really HUD on the appearance and the operating characteristic according to establish the model of the correction angle.
