Maximum-entropy field-mapping in the presence of correlated multipath

A generalization of Burg´s algorithm is described for the maximum-entropy (ME) field-mapping of a space-time series that is characterized by a non-Toeplitz cross-spectral (CS) matrix. Stability of the original Burg algorithm is retained, that is, the reflection coefficient is less then unity in magnitude at each recursion of the algorithm. Examples are included to illustrate applicability of the generalized algorithm to spatial mapping of correlated sources, as encountered in an under-water acoustic environment.
