Abstract

The invention discloses a diagnosis method of an array antenna. the method comprises the following steps: S1, obtaining an in-array directional diagram of array elements of an array antenna and the position of the center of the in-array directional diagram; S2, feeding port excitation I; S3, obtaining the positions of the M first measurement points and the first measurement data E of the electric / magnetic field of the array antenna at the M first measurement points; s4, according to the directional diagram in the array; the center of the directional diagram in the array is positioned; s5, calculating a difference value between the aperture field excitation I'and the reference aperture field excitation I'R, for a single array element, if the difference value is greater than a preset threshold value, determining the array element as a fault array element, and otherwise, determining the array element as a normal array element. According to the array antenna fault diagnosis method, the array antenna can be rapidly and efficiently diagnosed through less measurement data in combination with known priori knowledge of the array antenna, and the fault is positioned to a single array element, so that the array antenna fault diagnosis method has important significance for array antenna diagnosis on research and development and production lines.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to a diagnostic method, device, system and computer-readable storage medium of an array antenna. Background technique [0002] Antennas are widely used in radio systems such as communications, broadcasting, television, radar, and navigation. They play the role of spreading radio waves and are an essential device for effectively radiating and receiving radio waves. An array antenna is a type of antenna that is arranged regularly or randomly by no less than two antenna elements and obtains predetermined radiation characteristics through proper excitation. In recent years, array antennas have attracted much attention as an important development direction of civilian and military antenna technology. [0003] The array antenna is composed of multiple antenna elements. Each element is fed with a signal of a certain amplitude and phase to form a specific beam and realize beam sca...
