【摘要】:探鳥雷達已成為機場鳥擊防范、風力發(fā)電場鳥擊風險評估、鳥類自然保護區(qū)鳥情觀測與科學研究的重要工具。文中首先論述了探鳥雷達的主要組成部分。然后,分析了地面雜波、空域雜波和其他無關目標對探鳥雷達探測效果的影響,進而介紹了傳統(tǒng)的雜波抑制方法和相參雷達雜波抑制技術(shù),以及先進的探鳥雷達采用的目標檢測、目標跟蹤、目標顯示、數(shù)據(jù)記錄和雷達組網(wǎng)等數(shù)據(jù)處理技術(shù)。接著,給出了當前的探鳥雷達能夠獲取的目標軌跡、回波大小、回波強度、信號波動、飛行速度、飛行高度等反映飛鳥目標特性的主要指標。最后,描述了國內(nèi)外四種典型雷達探鳥系統(tǒng),并針對雷達探鳥技術(shù)的未來發(fā)展提出了一些思考及可行性建議。
[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.
