  • The MODE-TOEP algorithm is proposed to estimate DOA of coherent signals on a Uniform Circular Array (UCA). Firstly, the mode excitation method is used to transform the UCA in element space into a virtual ULA (VULA) in mode space. Then a Toeplitz matrix can be reconstructed to estimate DOA of coherent signals successfully. MODE-TOEP algorithm has less computational burden due to non-spatial smoothing. Simulation results show that MODE-TOEP algorithm is effective and has a better performance compared with conventional MODE-SS algorithm.
