Abstract

© 2017 SPIE. Detection of improvised explosive devices (IEDs) presents a significant challenge for stand-off sensors. IEDs can be constructed from a wide variety of materials and take many different forms. Forward-looking and side-looking sensor systems attempt to detect targets at significant stand-off but typically observe a potential threat area over a wide range of aspect before detection and classification is attempted. Furthermore, in practical detection scenarios IEDs are obscured preventing unhindered line-of-sight interrogation. Both of these characteristics can lead to target signatures which become incoherent over time. In this paper we investigate an advanced imaging technique designed to improve image quality of obscured targets utilizing a wide-band RF array. Specifically, we consider buried targets and obscured roadside targets. Results are presented in terms of improved signal to clutter ratio of image reconstructions based on simulated and experimental GPR collections.
