Experimental Study of X-Band Radar Scattering Characteristics of Aircraft Wake Vortices
Pages: 406-410
Year: Issue:  6
Journal: Radar Science and Technology

Abstract: 利用X波段新型多普勒天气雷达,针对起飞阶段的某型号运输机进行了飞机尾流探测实验.在显著偏离垂直入射方向的观测条件下,实验获得了尾流散射的中频回波数据.文中介绍了实验概况和数据处理流程,处理并分析了实验数据,获得了尾流散射的时间-多普勒速度谱和雷达散射截面(RCS)估计结果,在此基础上研究了尾流的雷达目标特性.结果表明,尾流具有多根时变谱线,各谱线的位置、强度近似呈对称分布;在距离雷达1.4km处,...
