GPR Image Decluttering Using Matrix Pencil Based Trace Filtering Method
Ground Penetrating Radar (GPR) measurements can suffer from large amount of noise and clutter. Current methods, such as time gating and background averaging, mostly applied to remove reflections from air-ground interface do not perform well when removal of extraneous, very strong and non-uniform clutter signals originating from the objects in the surveyed area other than the target is needed. T...
متن کاملGPR Full Waveform Sensitivity Analysis using a FDTD Adjoint Method
Coarse structures involving low electrical contrasts can be profitably imaged by means of cheap and relatively simple methods such as travel time tomography, whereas fine structure involving sub-wavelength detail can only be recovered by inverting full-waveform data. Despite its complexity and high computation costs, full-waveform inversion of GPR data has become a popular tool for high-resolut...
متن کاملSubsoil Water
In March, last, Drs. Cunningham and Lewis put ia motion experiments to test the value of Professor Pettenkofer's theory of the propagation of cholera, in the neighbourhood of Calcutta, by daily measurements of the level of subsoil water: they a^s0 caused similar experiments to be undertaken in Oudh. The measurements are now ordered by the Government of India to be carried out in every military ...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Railway track inspection using GPR
Ž . Swiss Federal Railways SBB inspect their railway tracks at regular intervals. The first step of track renewal planning is a geotechnical study. Inspection is focused on the thickness of the ballast, on subsoil material penetrating upwards into the ballast and on geotechnical properties of subgrade and subsoil materials. Up to now, the inspection has been done mainly by digging trenches at e...
