Avian radar system has been developed for bird-aircraft strike hazard avoidance. Two representative systems, which are countrywide and airport-based avian radar systems, are surveyed to summarize the state-of-the-art in this research field. Avian radar experimental system built by Beihang University is introduced in detail, including system architecture, performance analysis, and processing algorithm for bird target detection and tracking. This radar is operated in horizontal and vertical positions alternatively for scanning, and some experimental data are collected, respectively, at reservoir and airport. After processing of background subtraction, noise suppression, target information extraction, tracking and data fusion, a fused image containing bird targets and aircraft is provided. Finally, improvement suggestions on radar antenna, processing algorithms and risk assessment models of bird-aircraft strikes are given. Moreover, a scheme for practical systems applications at airport is proposed.
