摘　　要：为提高军事训练的效率,根据某型飞行模拟器的气象雷达成像特点,开发了基于OpenGL的机载气象雷达图像仿真系统。通过模拟机载气象雷达向空间脉冲发射回波,计算云层面积、云层厚度、云层中含水量等物理信息。基于真实的雷达探测过程的建模仿真分析雷达回波信息,根据回波强度的不同建立了基于RGB颜色空间模型的气象成像,基本实现了在复杂气象条件下对雨云回波的屏幕测绘,并解决了模拟余晖扫描显示的问题,有效地改善了军事训练的成像效果。According to the features of one kind of flight simulator radar image, and based on GpenGL we developed the airborne meteorological radar image simulation system which aim to improve the efficiency of drill. Via simulating airborne meteorological radar pulse echo, the physical data information in a limited range on the thickness and area of the cloud is calculated. To analyse the radar pulse information base on the model simulation of real radar detecting process and build the airborne meteorological radar image based on simulation RGB color space model. The simulation system basically realized the screen mapping on strong echo of thunder storm under complex weather condition and solved simulating surplus sunshine scanning problem. Therefore, the effect of drill is improved efficiently.
