Source Identification in Remote Sensing Problems

SIAM Review, 1991
In remote sensing problems where a wavefield encounters a scattering body, the source wavelet can be extracted by calculating surface integrals which involve the incident or scattered wavefield. No knowledge of the scattering body is required. The general formulas require the field and its normal derivative; however, some geometries require only the ...

Meshless Collocation Method for Inverse Source Identification Problems

Advances in Applied Mathematics and Mechanics, 2015
AbstractA novel meshless scheme is proposed for inverse source identification problems of Helmholtz-type equations. It is formulated by the non-singular general solutions of the Helmholtz-type equations augmented with radial basis functions. Under this meshless scheme, we can determine smooth source terms from partially accessible boundary measurements

The source identification problem in electromagnetic theory

Journal of Mathematical Physics, 1997
The problem of the identification of the electromagnetic source which produces an assigned radiation pattern is ill-posed: the solution is, in general, not unique and it does not depend continuously on the data. In this paper we treat in detail these two aspects of the problem.

Source identification problems for abstract semilinear nonlocal differential equations

Inverse Problems and Imaging, 2022
<p style='text-indent:20px;'>In this paper, we investigate a source identification problem for a class of abstract nonlocal differential equations in separable Hilbert spaces. The existence of mild solutions and strong solutions for the problem of identifying parameter are obtained.
