Abstract

The invention provides an anti-interference method and device for array antennas. The method comprises following steps: N sets of digital complex signals which are processed with digital quadrature interpolation and are corresponding to N radio frequency channels are received, wherein the N is an integer larger than 1; a cross correlation coefficient matrix corresponding to the N sets of digital complex signals is generated; a constraint steering vector consistent to a preset self-adapted selection condition is calculated on the basis of the cross correlation coefficient matrix; an anti-interference weight value is determined in combination with a preset optimal criterion on the basis of the constraint steering vector. By use of the provided anti-interference method and device for array antennas, the problem in the prior art of weakened anti-interference effects of the array antennas at some angles is solved.

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...
