Performance Analysis of MUSIC for Conformal Array

The manifold of 3D conformal array geometry is modeled and the classical high resolution direction-of-arrival (DOA) estimation method-multiple signal classification (MUSIC) algorithm is replanted into conformal array in this paper. The performance of MUSIC for conformal array is analyzed in detail, including its variance and corresponding Cramer-Rao bound (CRB). Computer simulation for the performance comparison between conformal array (conical array, cylindrical array, and spherical array) and planar array (uniform linear array and uniform circular array) is demonstrated. Some conclusions of MUSIC performance evaluation for different array geometry are reached.
