攻击型无人机射频半实物仿真中的相似性研究

Study on Conformity of Radio Frequency Simulation for Attack UAV

介绍了某攻击型无人机射频半实物仿真系统,指出了实验室目标阵面视角范围的限制和转台模拟无人机姿态运动存在的问题对仿真的影响,通过引入动参考坐标系以及转台坐标系来描述无人机-目标相对运动,在现有的仿真实验条件下可以复现真实的无人机与目标运动状态。仿真试验结果与飞行试验对比证明,该方法是有效的。

A brief introduction of radio frequency hardware-in-the-loop(HIL)simulation system for Attack Unmanned Aerial Vehicle(AUAV)is given.Influence upon simulation owing to LOS angle limitation of the target array antenna plane and the problem of simulating UAV attitude motion by 3-axis rotation table is pointed out.Through introducing dynamic coordinate system,the relative motion between target and UAV conforming with actual attack course is simula- ted.The method is proved to be effective from practice.
