Abstract

The invention discloses a Terahertz compact range test system based on an electronic scanning antenna. The system comprises a dark room, a target to be tested, a fixing device, a vector network analyzer, a Terahertz vector network expansion module, a computer, an electronic scanning antenna and a feed module; both the electronic scanning antenna and the feed module are positioned in the dark room;the electronic scanning antenna and the Terahertz vector network expansion module are in control connection via the feed module. According to the abovementioned mode, a miniature, quick and convenient Terahertz compact range with low cost can acquire the radar reflection section of the target to be tested or the distant field directional diagram of the antenna to be tested, the brand new active electronic scanning antenna is used for replacing the original emitting surface or holographic grating, so that the system cost is reduced, the using space is reduced, and meanwhile, the miniature compact range quick test capacity is provided.

Description

technical field [0001] The invention relates to the fields of industrial detection, scientific experiments, test measurement, etc., and in particular relates to a terahertz compact field test system based on an electronically scanned antenna. Background technique [0002] Communications, radar, navigation, remote sensing, radio, television and other radio technology equipment all transmit information through radio waves, and all require radiation and reception of radio waves. In radio technology equipment, the device used to radiate and receive electromagnetic waves is called an antenna. The antenna is an essential and important part of the radio information dissemination system. The core parameters such as the pattern of the microwave to terahertz antenna can be tested by using the vector network analyzer and the vector network expansion module, so as to obtain the main performance parameter indicators of the antenna. [0003] At present, there are mainly far-field method,...
