基于L1导航算法的无人机空中拦截系统研究与实现

Research and Implementation of UAV Air Interception System Based on L1 Navigation Algorithm

针对低空无人机安全问题,设计了一套基于L1导航算法的无人机空中拦截系统。系统由拦截机本体、运行L1导航算法的飞行处理器、具有拦截功能的飞行控制器以及可视化地面站软件组成。系统在得到空中目标机的三维位置信息后,由L1导航算法指定拦截机引导策略,拦截机则在机载飞行控制器的控制下飞行至目标位置,实现对空中目标机的伴飞与拦截,目标机与拦截机的实时位置信息以及拦截效果可通过可视化地面站软件进行实时显示。利用Matlab对该系统所设计的拦截策略进行了仿真验证,并在此基础上,利用多无人机试验平台进行了室外飞行试验验证,飞行试验结果验证了系统的有效性。

Aiming at the safety problem of low altitude UAV,a UAV interception system based on L1 navigation algorithm is designed.The system consists of the interceptor,the flight processor based on L1 navigation algorithm,the flight controller with interception function and the visual ground station software.After the system obtains the three-dimensional position information of the target UAV,the guidance strategy of the interceptor is specified by the L1 navigation algorithm,and the interceptor flies to the target position under the control of the airborne flight controller to realize the accompanying flight and interception of the target aircraft.The real-time position information of the target UAV and the interceptor as well as the interception result can be displayed through the visual ground station software.Finally,the interception strategy designed by the system is simulated and verified by Matlab.On this basis,the outdoor flight test is carried out by using the multi-UAV test platform,and the flight test results verify the effectiveness of the system.
