An anti-detection flight method for drone swarm based on photosensitive sensing
Existing studies mostly focus on sensing external environments and targets by drones, with limited attention to onboard perception of active external detection. To solve this problem, this paper proposes a photosensitive sensing anti-detection flight method for drone swarms. First, we develop a compact photosensitive sensor unit that measures ambient directional illumination at each point in space around the drone. Based on the above, we devise an anti-detection evasion strategy by combining online observation and history weighting, and couple it with a risk propagation anti-detection model to enable local evasion knowledge sharing and coordination within the swarm. In addition, an onboard photosensitive experimental platform is constructed for local directional light-intensity observation. Experimental results show that, in the single-drone scenario, compared with no avoidance strategy, the proposed approach reduces the mean exposure time inside the threat area by 27.90%, with a maximum heading change of 46.80° during avoidance. For the swarm-cooperative case, our approach can reduce the average swarm exposure time by 26.62% compared with the strategy without anti-detection, and by 9.39% compared with the traditional velocity averaging strategy. The results provide a useful reference platform, experimental data, and theoretical support for coordinated anti-detection flight in drone swarms.
