Abstract

The invention provides a measuring system and method of a short wave antenna directional diagram and a gain, and aims at improving the measuring precision of the short wave antenna directional diagram, measuring the gain of short wave antennas and displaying the short wave antenna directional diagram in real time. The implementation method comprises the steps of determining frequency points of thedirectional diagram and the gain which need to be measured; selecting antennas for a second drone of a standard antenna assisting testing subsystem; using a ground testing subsystem to control the standard antenna assisting testing subsystem and a testing liftoff platform subsystem to calibrate level values on working frequency points of to-be-tested short-wave antennas, and using a differentialnavigation reference station subsystem to correct the relative position of the drone; using the ground testing subsystem to control the testing liftoff platform subsystem to measure level value data on the working frequency points of the to-be-tested short-wave antennas, using the differential navigation reference station subsystem to correct a navigation track of a first drone, and using the ground testing subsystem to display measurement data in real time and draw the directional diagram; using the ground testing subsystem to calculate the gain values of the to-be-tested short-wave antennas.

Description

technical field [0001] The invention belongs to the technical field of antenna measurement, and relates to a system and method for measuring the pattern and gain of a short-wave antenna, which can be used to obtain the gain and pattern of the short-wave antenna. Background technique [0002] Short-wave communication still plays an important role in the communication field of various countries. Short-wave antenna is the core equipment in short-wave communication. The performance of the antenna will directly affect the actual communication effect. In order to accurately measure the pattern and gain of the antenna, the measurement of the conventional antenna is carried out in the microwave anechoic room. However, due to the large size of the short-wave antenna and the extremely long distance of the far field of the antenna, the microwave anechoic room does not have enough space for measurement. At present, people mainly obtain the pattern and gain of the short-wave antenna thro...
