A Parameterized Hough Transform Approach for Estimating the Support of the Wideband Spreading Function of a Distributed Object

摘要

A multidimensional Hough transform is used in conjunction with continuous wavelet transforms to aid in solving a parameterized inverse problem. The inverse problem under consideration is the characterization of distributed scatterers by means of active wideband remote sensing. Wavelet transforms are used to obtain estimates of distributed scatterers in the delay/scale plane. From a noisy wavelet transform estimate, the Hough transform is used to estimate a support region which is directly related to the physical parameters describing the distributed object.
