Description

technical field [0001] The invention belongs to the field of short-wave receiving antenna state detection, and in particular relates to a system and method for aerial three-dimensional wireless automatic detection of short-wave receiving antenna efficiency. Background technique [0002] When manually inspecting the shortwave receiving antenna, relying on the existing means, only the basic parameters of the antenna can be measured, such as impedance characteristics and standing wave ratio. These indicators represent some characteristics of the antenna, but cannot fully reflect The real receiving efficiency when the antenna is working, therefore, there is a problem that the working condition of the antenna is still not good after the inspection, and there is a lack of a method that can automatically measure the efficiency of the receiving antenna quickly, accurately and conveniently. [0003] There are many domestic research results on the fault detection equipment for shortwa...
