Abstract :
In this paper, the spectral correlation conjugate cyclic MUSIC algorithm with the Sum-MRLA configuration is presented. The algorithm constructs a pseudo-data matrix of 2N-1 virtual sensors from M-sensor Sum-MRLA to estimate DOA; thus the effective array aperture can be enlarged. Theoretical analysis and computer simulations show that, at each cyclic frequency the new method can estimate more DOA with fewer sensors
