Abstract
The results of numerical electromagnetic simulation and analysis of a set of positive-adaptive UAV radar signals are presented. These signals are simulated via the modeling of materials that enclose “building-type” structures with a series of connected dielectric materials. For example, windows, walls, and doors are each modeled separately by a combination of suitable material properties. Signals from objects that are embedded within these “building-type” structures are also simulated via the development and application of appropriate geometrical and materials models. Analysis of the resulting simulated “leakage signals” that penetrate the surfaces of these “building-type” structures and are backscattered from embedded objects within the indoor environment back to the simulated outdoor environment are presented. The results of a signal analysis are presented in two categories. The first set of results illustrates signal trends that can be exploited by “position-adaptive” mini-UAV's to isolate effective “leakage points” in “building-type” structures. The second set of results illustrate signal trends from embedded objects after a particular “position-adaptive” mini-UAV has converged to a “leakage point.”
