Iterative calculation of the second derivative of the gravity field using Richardson’s formula

الملخص EN

An improved version of Richardson's formula has been introduced in a new iterative form to increase the convergence ؛٠ the Taylor series, which is the funda-mental basis for calculation of the second derivative of the potential field.

Two sets of filter coefficients have been developed.

These coefficients have good re-sponses in the frequency domain when compared with the theoretical amplitude response of the second derivative operator.

A comparative study of the derived sets along with other coefficient sets is also presented.
