Abstract
The time-domain wideband beamforming algorithm can output continuous waveforms in the time domain, which can improve the processing performance of array system. The time-domain wideband beamforming algorithm of the Frost structure needs to compensation the phase of the incident signal to the same angle through pre-delay. This paper proposes a robust Frost time-domain wideband beamforming method based on phase compensation, which integrates the pre-delay into the coefficient solution of the filter, suppresses the interference by adjusting the main lobe, and constraining the width of the main lobe to increases the robustness of the beamformer, its effectiveness is proved by simulation experiments.
