Abstract:

The weather radar network is especially suitable for observation of large-scale bird activities on the continent. This paper first introduces the relatively mature bird early warning systems based on the weather radar networks in the United States and Europe, and makes a comparative analysis of their performance. Then, the echo characteristics of the weather radar bird target are analyzed in terms of echo amplitude, altitude distribution, flight speed and direction, and then the bird information extraction technologies including clutter suppression, weather information elimination, bird target feature extraction, machine learning, and cross validation are discussed. On this basis, the applications of bird detection with the weather radar network in bird ecology research and bird strike avoidance are introduced. The preliminary idea of establishing a national bird surveillance system based on the weather radar network in China is discussed in terms of detection coverage and weather radar system performance.

Key words: weather radar, clutter suppression, machine learning, bird warning, bird strike avoidance
