一种基于HLA的飞机训练模拟器的研制

Research and Implementation of HLA Based Training Aircraft Simulator

具有综合作战训练能力的飞机训练模拟器不但需要模拟飞机的飞行和雷达、惯导等航电设备,还需产生逼真的战场环境及视景音效,并且要模拟出各个分系统之间的相互协作和复杂的交互。在实现这种模拟器时,采用HLA/RTI作为其体系结构和支撑平台,使设备仿真器间也实现互操作,可以提高系统的伸缩性和可扩展性。基于目标和地面电磁反射特性数据库的信息和雷达探测模型,实现了雷达图像动态生成。基于黑板模型和虚拟机技术,构建了易于修改和演化的CGF系统。

The aircraft simulator capable of synthetic battle training needs not only to simulate flying and avionics, such as radar, inertial navigator, but also to generate the high fidelity visual image and voice of war field situation. Besides this, it must simulate the interactivities and collaborations among the subsystems. Based on HLA/RTI architecturally, the interoperation and reusability of the device simulators, which are subsystems of the aircraft simulator, are assured, and the aircraft simulator becomes more flexible and extendible. By the use of the electromagnetic reflection information of targets and ground in database, the radar detection model can generate radar image dynamically. Based on the techniques of blackboard model and virtual machine, a CGF system is implemented, which is easy to modify and evolve.
