By exploiting favorable characteristics of a uniform linear array (ULA), the far-field approximation (FFA) method reduces the deterioration of most high-resolution bearing estimation techniques due to the invalidity of the planar wavefront assumption when near-field sources exist. We first present a new technique that provides better performance than existing bearing estimation techniques for cyclostationary signals. Then, the proposed technique incorporating with the FFA method is proposed to estimate signal bearings in the presence of near-field sources without revising the planar wavefront assumption. Several simulation examples confirm the theoretical work and show the effectiveness of the proposed technique
