Fourier analysis of the signal scattered by three-dimensional objects in translational motion. I, II
Abstract
A general theory of scattering by a three-dimensional moving object immersed in a plane wave is developed. The explicit time dependence of the scattered fields at a stationary observer is calculated with emphasis on the Fourier spectra of these time-dependent signals. Then, the general theory is applied to the fields scattered by small particles and the fields scattered by dielectric spheres of arbitrary size. The effect of the time dependence of the incident wave is investigated assuming the latter to be a plane wave with sinusoidal time-dependence modulated by a Gaussian envelope.
