The performance of DOA estimation will be distorted in the presence of dielectric dome in the Dielectric Dome Array(DDA) because the dielectric dome diverge the planar wavefront into non-planar wavefront inside it. We proposed a far field approximation(FFA) method in this paper to improve the performance based on DDA. This method first reconstructs a FFA covariance matrix, which is Toplitz and approximate to the far field data covariance matrix, and then the high-resolution eigenstructure techniques can be utilized to estimate the DOAs without revising the planar wavefont assumption. Simulation results confirm the theoretical work.
