TWO DIMENSIONAL STRAKHOV'S FILTER FOR EXTRACTION OF POTENTIAL FIELD SIGNAL*

A two dimensional linear filter operator based on Strakhov's method for the extraction of a potential field signal (gravity or magnetic) from a background of homogeneous random noise has been developed. An algorithm to solve for the coefficients of the operator is given together with the corresponding computer program in FORTRAN language. It may be used on any machine using FORTRAN IV. A few examples of the operator are also included.
