Abstract

The invention discloses an external field antenna pattern testing method. A test station is looked for as an auxiliary antenna and an antenna rotation platform system are installed on a mobile maneuvering device and move around a measured antenna; a total station in an optical surveying and mapping instrument is innovatively adopted for locating the angle and the distance when the antenna moves and a test station with the corresponding deviation angle can be accurately located. By the adoption of the test station locating method where the maneuvering device, the total station in the optical surveying and mapping instrument and the antenna rotation platform system are combined, the measuring angle can be located accurately to local conditions under conditions of an external field. Meanwhile, after the measuring station is located, the total station is used for automatically tracking azimuth information and a horizontal scan frame on the antenna rotation platform system is used for moving the auxiliary antenna, so that the auxiliary antenna can be accurately located at all measuring stations within a certain measurement angle range at each measuring station, the moving frequency of the maneuvering device is lowered, errors brought by moving of the maneuvering device are reduced and the testing efficiency is improved.

Description

Technical field

[0001] The invention belongs to the technical field of test and measurement, and more specifically, relates to a test method of antenna pattern under external field environmental conditions. Background technique

[0002] As antennas are used more and more widely in radio systems such as radar and communications, the measurement of antennas has attracted more and more attention. There are many technical indicators for antenna measurement. The antenna pattern characterizes the antenna’s ability to radiate electromagnetic waves in space and reflects the antenna’s performance indicators and working status. Therefore, measuring and analyzing the antenna pattern can analyze the antenna’s radiation characteristics. Provide analysis data for the debugging, installation, maintenance, and overhaul of the antenna during use, and determine whether the performance index of the antenna meets the requirements and whether the antenna is faulty.

[0003] At present, the test of ant...
