A generalization of Capon's maximum-likelihood technique for detection
and estimation of seismic signals is introduced. By using a multi-dimensional
autoregressive approximation of seismic array noise, we have developed
a technique to use Capon's multi-channel filter for on-line processing.
Such autoregressive adaptation to the curent noise matrix power spectrum
is shown to yield good suppression of mutually correlated array noise
processes. As an example, this technique is applied to detection
of a small Semipalatinsk underground explosion recorded at the ARCESS
array.
