Spatio-Temporal Spectral Analysis by Eigenstructure Methods,
STANFORD UNIV CA INFORMATION SYSTEMS LAB
Pagination or Media Count:
This paper presents new algorithms for estimating the spatio-temporal spectrum of the signals received by a passive array. The algorithms are based on the eigenstructure of the covariance and spectral density matrices of the received signals. They allow partial correlation between the sources and thus are applicable to certain kinds of multipath problems. Simulation results that illustrate the performance of the new algorithms are presented.
