摘　　要：简述了研究雷达天线风荷载和变形特性所用的测试仪器、测试方法及数据处理。给出了抛物面及圆锥形两种雷达天线的主要研究结果 ,结果表明对于所研究的构形圆锥天线的阻力和方位力矩系数分别为圆抛物面天线的 1.34倍和 4 .0倍 ,而最大弹性变形量却仅为圆抛物面天线的 75 % 。The test instruments, methods and data proccessing for wind load and deformation characteristics of a radar antenna are describled briefly. The important study results obtained for conic and paraboloid antennas show that the coefficients of drag and orient moment of conic radar antenna are 1.34 and 4.0 times as large as those of paraboloid antenna, respectively. However, the maximum elastic deformation of conic antenna are 75 per cent of that of paraboloid antenna. The completely different characteristics of wind load and deformation of these two kinds of radar antennas were analysed in this paper.
