摘要

摘要: 介绍了雷达探鸟系统的研究现状,包括以鸟击危害咨询系统为代表的大型雷达探鸟系统和以Accipiter为代表的机场雷达探鸟系统.基于X波段海事雷达搭建了"雷达探鸟实验系统",分别验证了其在水平和垂直两种扫描方式下探鸟的可行性.本系统在两种扫描方式下采集的两组探鸟雷达图像序列,分别由飞鸟目标提取算法进行处理.经过背景差分、噪声抑制、目标信息提取和数据融合,将鸟情信息从原始雷达图像中提取出来,并将其与卫星地图或高度坐标系相融合,融合图像直观地反映了探测区域内飞鸟目标的分布情况.最后,对国内外雷达探鸟系统的性能作了比较分析.

Abstract: State of arts of researches on avian radar systems were introduced, including large avian radar system represented by avian hazard advisory system (AHAS) and airport-based avian radar system represented by Accipiter. An avian radar experimental system was built based on X-band marine radar, and its bird detection feasibility was confirmed separately by operation in alternating horizontal and vertical position for the survey. Two series of avian radar images, which were collected under two scanning modes, were processed respectively by bird target extraction algorithm. After processing of background subtraction, noise suppression, target information extraction and data fusion, avian information was extracted from raw radar images and combined with satellite map or height coordinate system, so flying bird targets distribution situation in survey region was shown visually by fusion images. Finally, performances of avian radar systems at home and abroad were compared and analyzed.
