Fast algorithm for joint direction-of-arrival and frequency estimation
Xiaohua Tian · Chinese Journal of Radio Science · 2003
A computationally attractive algorithm based on the propagator method is proposed for simultaneous estimation of the direction-of-arrivals (DOA) and frequencies of multiple narrowband signals received at spatially separated sensors. The frequencies are found by the eigenvalues of a constructed low dimension matrix. The arrival angles are then estimated using the associated eigenvectors as well the estimated frequencies. Simulation results are presented to demonstrate the effectiveness of the algorithm and its comparative estimation performance.
