航空鸟击雷达鸟情探测研究

鸟击问题是全世界航空业共同的难题,受到国际学术界的普遍关注.基于雷达的鸟情探测的研究取得了很大进展,在一些发达国家已经建立起实用的雷达鸟击预警系统.本文首先总结了雷达鸟情探测研究的概况,介绍国外雷达鸟情探测系统的发展现状,鸟类雷达目标回波信息的特点、识别和检测方法.然后介绍了雷达鸟类目标探测的新进展:地理信息系统(GIS)、人工神经网络、计算机网络等新技术应用于雷达鸟情探测系统,构成了高效、实时的三维雷达鸟情探测网.最后提出了雷达鸟类识别研究的未来发展方向.

Research on Radar Avian Detection for Aviation

The bird strike hazard is a worldwide problem to aviation,which has received prevalent attention from international academe.The studying of avian detection based on radar has made much progress and some practical radar avian surveillance systems have been set up.A survey of research on radar avian detection,including progress actuality of foreign radar avian detection system,the characteristics of bird echo and the method of identification and detection,are presented.The new research are proposed in three aspects,Geographic Information Systems(GIS),Artificial Neural Network(ANN) and computer network,which are combined with radar avian detection system to set up a high-efficient,real-time,3D radar avian detection network.Finally,several research topics in future are suggested.
