In this paper, integration of an UWB array-based time-domain radar sensor in a vehicle-mounted multi-sensor system for landmine detection is described. Dedicated real-time signal processing algorithms are developed to compute the radar sensor confidence map which is used for sensor fusion. Performance of developed algorithms for stand-alone GPR sensor and multi-sensor suit is verified experimentally.
This paper presents an experimental evaluation procedure for a landmine detection GPR with a single transmit antenna and a receive antenna array. The procedure includes calibration of the ultra-wideband array, estimation of its footprint and cross-range resolution for different size of the aperture, checking the capability to image landmines buried within the array aperture. For the evaluation, the...
Comparison of different techniques for short-range UWB radar imaging has been performed based on experimental data. To acquire experimental data, a video-impulse radar with a specially developed antenna system with a single transmitter antenna and an array of receiver antennas has been used. Topology of the receiver array was made in such a way that the footprint of the receiver array does not have...
