  • To improve the ability of avian radar to process bird information, a statistical analysis method for the bird situation around airport is proposed based on avian radar data. By accumulating a large amount of avian radar data, hotspots of the activity area of bird targets can be determined and taken as a reference point to realise lifecycle management of each bird target from initiation to continuation and finally death. In the process of target tracking, combined with the particle filter method, the probability of several possible events is estimated, leading to completion of the data association and real-time statistics for the number of targets. The simulation results reveal that this method is superior to the traditional logic method regarding the timeliness of multi-target initiation. With the application of the proposed method to avian radar data, the bird population and its basic activity rules can be discovered by fixing the bird habitats around the airport.
