MULTIPLE-SOURCE WERNER DECONVOLUTION

A reformulation of the Werner deconvolution algorithm using the analytic signal is extended to multiple source bodies. The extended algorithm involves solving a linear least-squares problem; the coefficients so obtained determine a complex polynomial whose roots define the locations and depths of the body contacts. The extended algorithm has been used to map the structure of the Cobb offset zone of the Juan de Fuca Ridge from aeromagnetic data; both the top and bottom of the spreading center basalts can be delineated. Connections between the multiple-source Werner technique and CompuDepthTM are discussed.
