In this paper, vehicle-mounted ultra-wide band (UWB) radar is studied for detection of roadside improvised explosive devices (IEDs). Simulations and measurements have been performed to study the radar system set-up, target scattering, and data processing. The challenges of UWB radar for target visibility within the ground clutter, locating with limited angular diversity, and discrimination of buried bomb shells have been encountered and explored. Possible solutions to overcome these challenges are investigated.
The goal of our research is to assess the capability of ultra-wide-band (UWB) radar for detection of roadside improvised
explosive devices (IEDs). Radar scattering signatures of artillery shells over a broadband frequency range, with
different Tx/Rx polarizations, and at various aspect angles have been explored based on simulation and indoor
measurement. Characteristics of IEDs versus clutter, wave penetration at different frequencies are also investigated.
Finally, visibility of IED targets is tested on a moving cart in outdoor settings, with IED targets on ground surface,
recessed, and buried underground at different distances away from the radar.
