Two-Dimensional NC-Music DOA Estimation Algorithm with a Conformal Cylindrical Antenna Array

Abstract

Non-Circular MUSIC (NC-MUSIC) algorithm with a conformal cylindrical array is included to analyze high performance 2-D Direction of Arrival (DOA) estimation. The actual radiation pattern of each microstrip antenna in the conformal array is introduced to analyze the performance of NC-MUSIC algorithm in practice. The simulations show that NC-MUSIC algorithm has a higher resolution than the standard MUSIC algorithm, and the maximum estimation number of NC-MUSIC algorithm is increased, too. In spite of the influence of antennas, NC-MUSIC algorithm achieves 2-D DOA estimation accurately.
