The traditional anti-bird methods for airports are inefficient due to their singleness. In order to solve this problem, an anti-bird system which disturbs the learning procedure of birds is presented. In the investigation, the anti-bird functional space is plotted into several parts, and a 3D anti-bird model with gradually-distributed complexity in height is established, by which a 3D system marked as A552 with the complexity being consistent with the bird distribution in height is proposed. The system includes such modules as artificial human, scaring eyes, broadcasting, electronic gun and artillery. Thus, it can drive birds in the aspects of vision, hearing and smell, and reduces the bird impact probability by more than 57 %.
