Avian radar on the rise: Current state and outlook

Abstract

An airport can perform actions to make itself less attractive to birds; however, it is very hard to eliminate all birds crossing the runway(s). Bird controllers on runways can help to disperse the birds, but they are limited to visual observations and notifications provided by ground staff. Normally, bird controllers will respond when birds are already within the boundaries of the airport. Radar can be used to observe birds before they enter the periphery of the airport and the controllers can position themselves at the correct location to disperse these birds. Using avian radar, more insight can be obtained about the environment of the airport, which can help to locate the major attractants and enable proper action to be performed. Despite avian radar having many benefits, the system also has its limitations. For instance, various forms of clutter can influence the performance of the radar. Avian radar is mainly used as a strategic tool. The aim of this paper is to show a method of implementing radar as a tactical tool by taking into account its limitations. It is concluded that an eight-step implementation programme might be a good way to start benefiting from the current possibilities and to gradually introduce tactical applications. To be able to fully use the capabilities of a bird detection system as an operational tool, an accurate warning system should be developed which must take into account the probability that a bird will follow a certain trajectory.
