Estimation of spatial and spectral parameters of multiple sources
Boaz Porat, B. Friedlander · IEEE Transactions on Information Theory · 1983
The problem of estimating spatial and spectral parameters of multiple sources by sensor arrays is considered. A parametric model is derived for the multichannel measurement vector. Tbe model parameters are the time delays and the autoregressive moving-average parameters of all the sources. A suboptimal parameter estimation procedure is proposed, and simulation results are presented to illustrate its performance.
