Abstract
In this paper we demonstrate the capability of an ultra-wideband software defined radar (SDRadar) implemented in commercial USRP SDR hardware to produce high-resolution images of sub-surface landmine-like targets. We formulate a half-space back-projection focusing algorithm for low-altitude nadir-looking airborne altimetric ground-penetrating SAR that accounts for dispersive and refractive effects of the air-ground interface. Performance of the SDRadar and focusing algorithm are shown in experimental results. This work has applications in the development of low-cost high-resolution UAV-based radar systems for landmine detection and other sub-surface imaging tasks.
