Abstract

The invention provides an anti-interference method and an anti-interference device for an array antenna. The method comprises the following steps of: receiving N groups of digital complex signals which are subjected to digital quadrature interpolation and corresponding to N radio frequency channels, wherein N is an integer greater than 1; generating a cross correlation coefficient matrix corresponding to the N groups of digital complex signals; by the cross correlation coefficient matrix, calculating a constraint steering vector which meets a preset adaptive selection condition; and based on the constraint steering vector, determining an anti-interference weight value in combination with a preset optimality criterion. The anti-interference method and the anti-interference device for the array antenna, provided by the embodiment of the invention, can solve a problem of weakening of anti-interference effect at some angles in the existing array antenna anti-interference technology.

Description

technical field [0001] The present application relates to the technical field of array signal processing, and in particular to an array antenna anti-jamming method and device. Background technique [0002] Wireless communication technology plays an increasingly important role in the field of modern communication, but because the wireless signal is extremely weak, it is vulnerable to various natural or man-made interferences and cannot be used. Therefore, it is necessary to introduce interference suppression technology to improve the resistance of wireless communication systems. Interference ability. In view of the fact that when the frequency of the interference and the useful signal are the same, the time domain and frequency domain anti-jamming technology will also suppress the useful signal while suppressing the interference, so the interference can be suppressed in the air domain according to the different spatial directions of the interference and the useful signal , t...
