Signal-subspace-based esprit-like algorithm for coherent DOA estimation
Zhan Jiang-shu · Journal of Communications · 2010
To consider the problem of DOA estimation in coherent environment,the most important issue is to try to eliminate the rank loss of the spatial covariance matrix.The influence of coherent signals on the subspace-based ultra-resolution DOA estimation algorithm was analyzed.Then a signal-subspace based ESPRIT-Like algorithm was proposed from the thought of matrix reconstruction.The simulation results demonstrate the validity and superiority of the proposed algorithm.
