Abstract :
Whittaker-Shannon interpolation formula instead of narrowband filter (NF) is used to interpolate the signal more precisely in wideband direction-of-arrival (DOA) estimation problem when the number of samples is highly limited. A novel algorithm named block FOCal Underdetermined System Solver (BFOCUSS) is proposed to solve this problem. The simulation results validate the superior performance compared with the other algorithms.
