摘　　要：甚低频系留气球缆绳天线是机动式车载甚低频通信系统的重要组成部分.该缆绳在作为气球浮空平台系留缆的同时,还需兼具甚低频段电磁波的天线辐射功能.本文针对甚低频辐射天线的电气特性及物理特性,通过对天线关键参数的计算、不同风速下的缆绳姿态及辐射方向图的设计仿真,在工程上以光电复合系留结构形式进行实现.最终结合理论分析与全系统通信试验数据对甚低频系留气球缆绳天线的辐射效能做出了综合评估,验证了该天线设计的正确性与高效性,为国内甚低频辐射天线的相关研究积累了一定的经验与数据.The VLF tethered balloon cable antenna is an important part of the mobile vehicle VLF communication system. While the cable is used as the tethered cable of the balloon floating platform, it also needs to have the antenna radiation function of VLF electromagnetic wave. According to the electrical and physical characteristics of the VLF radiation antenna, through the calculation of the key parameters of the antenna, the design and simulation of cable attitude and radiation pattern under different wind speeds are realized in the form of photoelectric composite tethered structure in engineering. Finally, combined with theoretical analysis and system wide communication test data, the radiation efficiency of VLF tethered balloon cable antenna is comprehensively evaluated to verify the correctness and efficiency of the antenna design. It has accumulated some experience and data for the related research of VLF radiation antenna in China.
