研究目的
Investigating the feasibility of using laser detection systems for effective monitoring and anti-reconnaissance of unmanned aerial vehicles (UAVs).
研究成果
The study concludes that laser detection is feasible for anti-reconnaissance of UAVs, especially using the focal plane reflected light which has a good return characteristic. The detection system can effectively detect and locate UAV targets within the field coverage of the UAV imaging system.
研究不足
The study does not consider the influence of atmospheric turbulence and other factors on the laser beam propagation. The simulation model uses an ideal single lens and a full mirror for the focal plane reflecting element, which may not fully represent real-world conditions.
