Aerial testing equipment for evaluating performance of short-wave antenna

Abstract

The invention discloses aerial testing equipment for evaluating performance of a short-wave antenna, and belongs to the technical field of communication. The aerial testing equipment is carried on anunmanned aerial vehicle and comprises a short-wave antenna, a power amplification module, a signal source, a data exchange and control module, a data transmission radio, a flight control module and apower module; the short-wave antenna is used for communicating with the to-be-tested short-wave antenna; the flight control module is used for obtaining state information of the unmanned aerial vehicle, receiving a flight control instruction sent by center control equipment arranged on the ground, and controlling the unmanned aerial vehicle to operate according to the state information of the unmanned aerial vehicle and the flight control instruction; and the data exchange and control module is used for obtaining the state information of the unmanned aerial vehicle and a power amplification output level value of the power amplification module after the unmanned aerial vehicle reaches the predetermined flight height, and transmitting the state information and the power amplification outputlevel value to the center control equipment through the data transmission radio, and the power amplification output level value is used for being provided for the center control equipment to evaluating the performance of the to-be-tested short-wave antenna.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an air test device for evaluating the performance of a short-wave antenna. Background technique [0002] As the throat of short-wave wireless communication air test equipment, short-wave antenna plays a very important role in the overall performance of short-wave wireless communication air test equipment. The indicators that characterize the performance of short-wave antennas can be roughly divided into two categories: one mainly characterizes the antenna feeding performance, such as voltage standing wave ratio, power capacity, grounding resistance, etc. These indicators can be accurately tested by network analyzers and other equipment; the other One category mainly characterizes the radiation performance of the antenna, such as gain, out-of-roundness of pattern, beam pointing, beam width, etc., which characterizes the ability of the antenna to transmit or receive electroma...

Problems solved by technology

[0003] The antenna radiation performance index is the key index to measure the antenna radiation performance. The commonly used short-wave antenna radiation performance index test method is: to test the performance of the typical direction of the antenna by testing instruments and meters at certain positions on the ground. This method can only test the antenna space. The performance is sampled and tested, and the antenna performance cannot be fully tested
