摘　　要：基于甚低频波导理论推导了机载拖曳天线辐射场的计算公式.计算了横磁波与横电波的高度增益,并分析了其随拖曳天线高度波动起伏的变化趋势;研究了拖曳天线辐射场随天线高度、天线倾角、接收方位角的变化特性.文章研究结果对机载拖曳天线的研制、应用具有重要的参考意义.Based on the wave-guide theory,the formulas used to calculate radiation fields excited by the airborne trailing antenna are deduced.According to the formulas,altitude gains are obtained,and the altitude gain fluctuation with the height of observing points is analyzed.Then,for the radiation fields excited by the trailing antenna,its variation characteristics with the antenna height,tilt angel and receiving azimuth angel are discussed,which has great reference value for trailing antenna study and application.
