Ultra-wide band radar is a growing interest for the enhanced capability of ranging, imaging, and multipath propagation. An ultra-wide band pulse imposed on a system provides a near impulse like response and is, therefore, more descriptive than a conventional monotonic pulse. Combining pulse inversion with ultra-wide band DORT (a French acronym for the decomposition of the time reversal operator) is a technique which could be used to for greater visibility of nonlinear targets via harmonic detection in the presence of larger linear scatterers. Energy can be selectively focused onto nonlinear scatterers in complex, inhomogeneous environments. This thesis1, will expand upon previous work, and demonstrate nonlinear detection and selective focusing with pulse inversion combined with DORT.
