A new algorithm for fast direction-of-arrivals (DOAs) tracking of multiple scattering sources is presented in this paper. The proposed method is based on total least square-ESPRIT (TLS-ESPRIT) and subspace updating. Compared with the DOAs estimation algorithms for sources without moving, our technique do not need search and it can update the moving scattering sources parameters fast and exactly. In addition, it can be applied to scenarios with multiple scattering sources that may have different angular power densities. The simulation results show the effectiveness of our method.
