In this paper, the development of an UWB arraybased time-domain radar sensor is described. The radar sensor is designed to be used within a vehicle-mounted multi-sensor system for humanitarian demining. The main novelty of the radar lies in the modular approach, design of the antenna system and waveform of the transmit antenna feeding pulse. The radar has focusing capability via near-field beamforming in cross-scan direction and migration in along-scan direction.Index Terms -Video-impulse radar, ultra-wideband antenna array, landmine detection.
