针对现有无人机反制技术仅对无人机本体进行干扰拦截,导致“治标而不治本”的问题,提出了一种非合作无人机地面站及飞手快速搜寻检测技术。首先,利用时间调制阵列天线信号测向方法测定非合作无人机地面站方位;然后,基于该方位信息使用透视投影计算地面站操作飞手在无人机挂载视觉设备中的投影尺寸;最后,重构轻量化目标检测网络,并通过目标投影尺寸信息辅助的网络选择机制实现飞手的快速检测。仿真和实验结果表明:所提技术可实现地面站及飞手的快速搜寻检测,其中在无人机平台上单次测向平均用时9.67 ms,平均测向误差1.08°;对飞手目标的图像检测帧率平均提升了52.98%,重构目标检测网络参数量平均减少59.6%,浮点运算速度平均下降37.7%。所提技术可为非合作无人机反制提供全新思路和方法。
To address the limitations of existing anti unmanned aerial vehicle (anti-UAV) technologies
which only focus on interfering with and intercepting UAVs themselves
resulting in a “symptomatic rather than fundamental” solution
a rapid search and detection technology aimed at non-cooperative UAV ground stations and operators is proposed. First
the direction of the non-cooperative UAV ground station is determined using a time-modulated array antenna signal direction-finding method. Then
based on this directional information
perspective projection is employed to calculate the projected size of the ground station operator in the UAV-mounted visual device. Finally
a lightweight target detection network is reconstructed
and a network selection mechanism assisted by target projection size information is implemented to achieve rapid operator detection. Simulation and experimental results demonstrate that the proposed technology enables fast search and detection of ground stations and operators. Specifically
the average single direction-finding time on the UAV platform is 9.67 ms
with an average direction-finding error of 1.08°. The image detection frame rate for operator targets is improved by an average of 52.98%
while the reconstructed target detection network reduces the parameter count by 59.6% and floating-point operations per second by 37.7% on average. The proposed technology provides a novel approach and methodology for anti-UAV measures.
