Antenna array direction finding method and device and electronic equipment

Abstract

The invention discloses an antenna array direction finding method and device and electronic equipment. The method comprises the following steps: constructing a coupling circuit based on bionics; obtaining an amplification phase difference output by an antenna array under the condition that the coupling circuit is arranged and a theoretical phase difference output under the condition that the coupling circuit is not arranged; determining phase difference amplification coefficients corresponding to different incident angles according to the theoretical phase difference and the amplification phase difference; when the antenna array is used for direction finding, the coupling circuit is arranged at the rear end of the antenna array, acquiring an initial incident angle obtained through direction finding of the antenna array, rotating the antenna array multiple times based on the initial incident angle to acquire an incident angle obtained through direction finding after each time of rotation of the antenna array; and when the incident angle obtained by direction finding of the antenna array is within the preset angle range of the corresponding incident angle when the phase difference amplification coefficient is maximum, obtaining a direction finding result. According to the embodiment of the invention, the miniaturization of the direction-finding antenna array can be realized whilethe direction-finding precision is ensured, and the antenna array is better suitable for a miniaturized platform.

Problems solved by technology

[0003] However, due to the limitation of the installation platform, the caliber that can be installed with the direction-finding antenna of the interferometer will inevitably be restricted.

However, the direction-finding performance of the small-aperture antenna array used by traditional interferometers is greatly reduced. Therefore, how to break through the direction-finding mechanism and constraints of the small-aperture antenna array to improve the direction-finding performance of the small-aperture antenna array is a technical problem that needs to be solved urgently.
