Abstract: 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 directionfinding 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 asisted 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 9.67ms ,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.
