“…Through the Wall Radar Imaging (TWRI) is at the forefront of modern radar technologies that may be applied in urban settings [1], [2]. The technology produces an image of the interior of a building, while the radar remains outside [3]- [7], and provides potentially vital intelligence to law enforcement officers, soldiers or rescuers in the event of a building collapse.…”

Abstract-Sensing through the wall using radar is a valuable capability. There is considerable work in generating radar images of the interior of a room by beamforming of the radar backscatter generated in a Synthetic Aperture Radar (SAR) configuration. However, high level interpretation of the scene is a more difficult task. In previous work a minimum distance classifier was successfully used to recognize various targets placed in the scene. The approach suffered from the dependency of target features on target location. This work presents a solution to this problem by bringing the target intensity profiles into alignment with the training data prior to classification. The alignment is performed by moving the intensity profiles between locations using an Autoregressive Moving Average (ARMA) model. The classification results before and after alignment show a marked improvement.

“…One needs not only to know if there is somebody inside a room but also where this person is. Radar systems are likely to provide an adequate answer to this kind of problem [1] and various processing methods are nowadays studied and considered to reach the final solution [2]. In this paper, we focus on ultra-wideband radar techniques [3,4] applied to through-the-wall human sensing.…”

“…It is supposed to be used for law-enforcement purposes during surveillance, reconnaissance and rescue missions (Ferris et al, 1999;Baranoski, 2008;Amin, 2011). Radar systems in general are based on the detection of reflected waves caused by scattering objects.…”
