On the accurate numerical evaluation of geodetic convolution integrals
In the numerical evaluation of geodetic convolution integrals, whether by quadrature or discrete/fast Fourier transform (D/FFT) techniques, the integration kernel is sometimes computed at the centre of the discretised grid cells. For singular kernels a common case in physical geodesy this approximation produces significant errors near the computation point, where the kernel changes rapidly acro...
متن کاملOn the Fresnel Integrals and the Convolution
The Fresnel cosine integral C(x), the Fresnel sine integral S(x), and the associated functions C + (x), C − (x), S + (x), and S − (x) are defined as locally summable functions on the real line. Some convolutions and neutrix convolutions of the Fresnel cosine integral and its associated functions with x r + and x r are evaluated. The Fresnel cosine integral C(x) is defined by C(x) = 2 π x 0 cos ...
متن کاملNumerical Evaluation of Wiener Integrals
Here, Jc F[x]w(dx) denotes the Wiener integral, and / F[0(u, ■ )]v(du) denotes an integral over some Euclidean space. In [1] Cameron determined a pair (v, 0) by imposing on (1.2) the condition that the formula be exact for polynomial functionals of degree ^3. Imposing the same requirement, Vladimirov [5] constructed a family of pairs (v, 6). In this paper we shall develop a class of approximati...
متن کاملNumerical Evaluation of Diffraction Integrals
This paper describes a simple numerical integration method for diffraction integrals which is based on elementary geometrical considerations of the manner in which different portions of the incident wavefront contribute to the diffracted field. The method is applicable in a wide range of cases as the assumptions regarding the type of integral are minimal, and the results are accurate even when ...
