【摘要】 三线、对数周期等大尺寸天线大量应用于通信台站与舰船上,然而,考虑到天线放置地点、工作频段、通信覆盖范围等要求,这类天线都具有较大的物理尺寸,在实验室环境和外场试验环境下都无法直接测量辐射方向图、发射效率、驻波比等天线性能指标。以大尺寸短波发射天线现场测试技术为研究对象,分析了大尺寸短波发射天线现场测手段的必要性与所存在的不足,在传统现场测试方法的基础上,提出了一种基于无人机的短波发射天线现场测试方法,对信台站与舰艇上大尺寸短波发射天线的设计、施工、调试、维修、以及现场系统联调等环节起到保障作用。更多还原

【Abstract】 A large numbers of large-size antennas such as three lines and logarithmic cycles used in communication stations and ships, the performance of the antenna on the communication and command of the whole system has a great influence. However, such as this kind of antenna has a larger physical size, in the laboratory and the field test environment can directly measure the radiation pattern, emission efficiency, standing wave ratio, such as antenna performance indicators. Based on the large size of shortwave antenna field testing technology as the research object, this paper analyzes the necessity of large size shortwave transmitting antenna field measurement method and the existing shortcomings of the traditional, on the basis of field test method, it proposes a shortwave antenna field test method based on unmanned aerial vehicle(uav), the letter stations and ships on the large size of shortwave antenna design, construction, commissioning, maintenance, and the field system alignment guarantee effect.更多还原
