摘　　要：为满足鸟击问题中对鸟情全天候实时预报的需求,提出一种基于外辐射源雷达探鸟新技术的研究方案,并开展相关实验研究。首先简述探鸟雷达的研究现状,其次介绍外辐射源雷达的基本工作原理,最后对实验场景配置进行说明并展示初步实验结果。实验结果表明,工作在特高频(Ultra High Frequency,UHF)频段的外辐射源雷达能够长时间对体长约30 cm以上鸟类目标进行跟踪定位,同时进一步说明外辐射源雷达技术是一种可行的飞鸟探测手段。该项技术的研发有助于为机场管理和鸟类生态学研究提供宝贵的鸟情数据。To meet the demand for all day and real-time forecasting in the bird strike problem,a new avian detection technology based on passive radar is proposed and related experimental research is carried out in this paper.It firstly describes the research status of avian radar,then introduces the basic working principle of the passive radar.Further,the experimental configuration is explained with the preliminary experimental results,which shows that the passive radar working in ultra high frequency(UHF)band can track and locate bird targets over 30 cm in length for a long time.At the same time,it further shows that the passive radar technology is a feasible means of bird detection.The development of this technology could provide valuable bird data for airport management and bird ecology research.
