Abstract
The low-precision computation at long-offset is problem in marine CSEM method. A high-precision linear filter program based on continuous Euler transformation was developed in order to solve Hankel transform for electric and electromagnetic method numerically. The continuous Euler transformation can accelerate the convergence of an alternating series. As a result of numerical evaluation, the new linear filter program based on continuous Euler transformation has better computation precision than conventional linear filter method based on convolution in spite of less number of filter coefficient. This new method will become a main method to calculate Hankel transform instead of conventional linear filter method.
