Title :
A multiresolution time domain approach to RF image formation
Author :
Bonneau, Robert J.
Abstract :
Conventional image formation approaches rely on frequency domain Fourier methods to create images of objects. Most rely on integrating spatial resolution in the Fourier domain and do not accurately factor in the spatial aperture function to create an image because of the uniform spatial sampling necessary for the Fourier transform. We propose a multiresolution approach based on a Greens function inverse scattering method that allows us to solve for the object function directly in the time domain thereby allowing a more accurate rendering of the object in question.
