Abstract

The anti-jamming capacity of traditional digital beamforming system is limited by the quantization accuracy of analog-to-digital converter (ADC).To address this situation

this paper proposes a hybrid analog-digital adaptive beamforming method.The interference signals are suppressed preliminarily by introducing the analog beamforming at the radio frequency channel

which prevents sampling saturation.Subsequently

the interference signals are suppressed with the digital beamforming technology.A hybrid analog-digital adaptive beamforming signal model is established.The proposed hybrid analog-digital method is theoretically derived

and its anti-interference performance is analyzed.The simulated results demonstrate that the proposed method can effectively reduce the impact of quantization accuracy and has the excellent performance for different interference intensities.Compared with traditional digital beamforming method

the superiority of the proposed method for blanket jamming suppression is also demonstrated.
