【摘要】:探鸟雷达已成为机场鸟击防范、风力发电场鸟击风险评估、鸟类自然保护区鸟情观测与科学研究的重要工具。文中首先论述了探鸟雷达的主要组成部分。然后,分析了地面杂波、空域杂波和其他无关目标对探鸟雷达探测效果的影响,进而介绍了传统的杂波抑制方法和相参雷达杂波抑制技术,以及先进的探鸟雷达采用的目标检测、目标跟踪、目标显示、数据记录和雷达组网等数据处理技术。接着,给出了当前的探鸟雷达能够获取的目标轨迹、回波大小、回波强度、信号波动、飞行速度、飞行高度等反映飞鸟目标特性的主要指标。最后,描述了国内外四种典型雷达探鸟系统,并针对雷达探鸟技术的未来发展提出了一些思考及可行性建议。
[Abstract]:Bird detection radar has become an important tool for bird strike prevention in airports, bird strike risk assessment in wind farms, bird observation and scientific research in bird nature reserves. In this paper, the main components of bird detection radar are first discussed. Then, the influence of ground clutter, spatial clutter and other unrelated targets on the detection effect of bird detection radar is analyzed, and the traditional clutter suppression methods and coherent radar clutter suppression techniques are introduced. And advanced bird detection radar, target tracking, target display, data recording and radar networking and other data processing technology. Then, the target trajectory, echo size, echo intensity, signal fluctuation, flight speed, flight altitude and so on, which can be obtained by the current bird detection radar, are given. Finally, this paper describes four typical radar bird detection systems at home and abroad, and puts forward some thoughts and feasible suggestions for the future development of radar bird detection technology.
