%X The performance of DOA estimation will be distorted in the presence of dielectric dome in the Dielectric Dome Array(DDA) because the dielectric dome diverges the planar wave-front into non-planar wavefront inside it. This paper proposes a Far Field Approximation(FFA) method to improve the performance based on DDA. This method first reconstructs a FFA Co-variance matrix, which is Toplitz and approximates 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.
