Multi-Channel Ultra-Wideband Short-Pulse Ground Penetrating Radar


© A. Yu. Grinev, A. V. Andriyanov, D. V. Bagno

The new multi-channel Ground Penetrating Radar (GPR) design is presented for search of objects in soil down to 1.2 meters depth. GPR uses ultra-wideband short-pulse signal generator, stroboscopic receiver with low-noise preamplifier, multi-channel pin-diode antenna switch, and seven-element antenna module based on screened T-horns with dielectric filling. All modules are mounted on the four-wheel cart. Designed GPR parameters, its hardware and software are discussed. 3D images of subsurface objects formed by GPR as well as results of objects geometry restoration are presented.
