| 摘要: |
| 效应实验研究是高功率微波（High Power Microwave，HPM）技术持续发展的基础，也是获取目标对象效应阈值的最重要手段。采用窄谱高功率微波实验系统开展了对某微小型固定翼无人机的动态扰乱效能验证测试。无人机的机载飞行数据表明，高功率电磁脉冲辐照无人机后，升降舵的偏转角由-5.9°急剧变化至-25°并出现“锁死”现象；方向舵的偏转角由0.1°剧烈变化至9.7°，随后出现非规则性地跳变。综合高功率电磁脉冲对无人机“后门”耦合效应过程分析认为，主要是扰乱了无人机飞控系统的中央处理器，致使其向舵机输出紊乱控制指令，直接引起升降舵和方向舵的偏转角发生剧烈变化，导致无人机进入失控状态并快速盘旋坠落。 |

| Abstract: |
| Effect experiment study is the basis for the continuous development of high power microwave(HPM)technology and is also the most important method of getting effect threshold for operational objective.Dynamic disruption experiment of a particular micro-small fixed-wing drone is carried out by using a narrowband HPM experimental system.The airborne flight data of the drone suggests that the deflection angle of the rudder rapidly changes from -5.9° to -25°,and is jammed suddenly.The deflection angle of the elevator changes from 0.1° to 9.7°,and irregular jump occurs subsequently.The analysis of “back-door” coupling effect of high power electromagnetic pulse is conducted for the drone.The results show that the central processing unit of flight control system of the drone is disrupted so as to output disordered control commands to the steering gear.These erroneous commands directly cause drastic change in the deflection angles of the elevator and rubber,making the drone enter an out-of-control state and spiral down rapidly. |
