摘要
针对目前激光制导武器数字仿真系统的不足,为了提高激光制导武器仿真的精度,在内场构建了一个对激光制导武器进行分析评估的半实物仿真系统。首先,根据RTX的仿真系统架构及控制系统软件的搭建方法和仿真系统的实现关键技术,提出了在内场模拟外场激光信号的能量、光斑大小及光斑位置的方法,并分析了三轴仿真转台实时控制系统模型的动态响应精度;最后,对半实物仿真、数字仿真及飞行脱靶量进行比较分析,结果表明,半实物仿真与飞行试验一致性更好,精度更高。证明仿真系统可为激光制导武器的分析评估提供了平台和依据。
In order to make up the shortage of digital simulation system for laser-guided weapons, a semi-physi- cal simulation system was designed in internal field to analyze and evaluate the performance of laser-guided weapons according to the requirements of simulation accuracy. First of all, the structure of simulation system based on RTX and the method to develop controlling programs were proposed. Then, the implementation method and key technolo- gies of the simulation system were discussed. It was simulated in internal field that the laser signal energy, spot size and spot location in external field and the dynamic response accuracy of the real-time control system of three-axis simulator were analyzed. Finally, miss distances of semi-physical simulation, digital simulation and flight tests were analyzed, and the semi-physical simulation system has been proved to be more accurate, which provides some refer- ence to analyze and evaluate the performance of laser-guided weapons.
