Analysis of discriminants for experimental 3-D SAR imagery of human targets [electronic resource] / Brigitte Chan, Pascale Sévigny, David D. J. DiFilippo. [Ottawa] : Defence Research & Development Canada, [2014] 1 vol. (unnumbered) : photos, graphs, ill. Includes bibliographic references. "Development of a prototype 3-D through-wall synthetic aperture radar (SAR) system is currently underway at Defence Research & Development Canada. The intent is to map out building wall layouts and to detect targets of interest and their location behind walls such as humans, arms caches, and furniture. This situational awareness capability can be invaluable to the military working in an urban environment. Tools and algorithms are being developed to exploit the resulting 3-D imagery. Current work involves analyzing signatures of targets behind a wall and understanding the clutter and multipath signals in a room of interest. In this paper, a comprehensive study of 3-D human target signature metrics in free space is presented. The aim is to identify features for discrimination of the human target from other targets. Targets used in this investigation include a human standing, a human standing with arms stretched out, a chair, a table, and a metallic plate. Several features were investigated as potential discriminants and five which were identified as good candidates are presented in this paper. Based on this study, no single feature could be used to fully discriminate the human targets from all others. A combination of at least two different features is required to achieve this"--Abstract. gccst Scientific research Sévigny, Pascale. DiFilippo, David D. J. Defence R&D Canada.
