Minimum Variance Multi-Frequency Distortionless Restriction for Digital Wideband Beamformer

Abstract

This paper proposes a digital amplitude-phase weighting array based a minimum variance multi-frequency distortionless restriction (MVMFDR) to aviod the frequency band signal distortion in digital beamformer and too short time delay line (TDL) requirement in analoge wideband TDL array.
