“In the field of low-altitude target detection, this paper proposes an active low-altitude target detection method based on the cat's eye effect, which provides solutions to address the current limitations in detecting low, slow, and small unmanned aerial vehicles. Expert xx established the detection system, which incorporates a control module, a laser emission component, a co-optical path panoramic scanning optical mechanism structure, an echo reception component, target detection, and visualization processing to achieve small target detection.”
