Abstract: The bearing and range estimation of near-field sources is studied and a new method is presented. The presented algorithm uses the dual-polarization array and second statistics to estimate DOA -range parameter of near-field sources. The method has the merits of good estimate precision and no needing spectral peak searching. Its effectiveness is approved by the simulation results. -
