Abstract
The scattering of a Multi-Gaussian Schell-model pulse from a sphere with semisoft boundaries within the accuracy of the first-order Born approximation is investigated. The analytic expression for the average intensity of the scattered pulse in the far zone is derived. The numerical calculations are performed in order to show the dependence of the average intensity of the scattered field on the incident pulse duration, the temporal coherence length of the incident pulse, the upper summation index and the effective radius of the medium. The effect of the boundary’s softness on the scattered intensity distribution is emphasized. It is shown that, comparing with that of scattering from a Gaussian sphere, the average intensity distribution of the pulse scattering from a sphere with semisoft boundaries has two or three peaks under certain circumstances.
