Fast Iterative Interpolated Beamforming for Accurate Single-Snapshot DOA Estimation

Abstract

A single-snapshot fast computational Fourier-based direction-of-arrival (DOA) estimation method is introduced. This method applies the fast Fourier transform (FFT) to sensor data and performs effective cancellation of spectral leakage caused by sidelobe interactions, leading to unbiased DOA estimates of multiple sources. Successful elimination of spectral… (More)
