 Obiettivi dell'insegnamento
 Geophysical methods based on the ecographic or tomographic principle generate the final results through a complex data processing procedure. The goal of the course is to introduce the student to the 2D and 3D data processing algorithms that are used to process geophysical data from seismic or georadar surveys. Algorithms are presented in simple and intuitive ways during the lectures and are tested by the student on real data during the laboratory hours.

 Risultati di apprendimento attesi
 The student: Knows the principles of the data processing algorithms used in seismic and georadar prospecting. Can define and apply a proper data processing sequence to produce a seismic or georadar 2D or 3D section. Knows how to select and optimize the input parameters required by each algorithm. Has some practice with a geophysical professional software so that he can rapidly get familiar with any other geophysical software that might be used by his company.

 Argomenti trattati
 1. Hints of signal theory: Fourier transform, linear systems, impulse response, transfer function, convolution, autocorrelation and cross-correlation, analog and digital signals, sampling, Nyquist theorem. 2. Processing of georadar data: hints on acquisitions, filters, time-calibration, background subtraction, gain, topographic corrections, velocity analysis, time-depth conversion, focusing methods for monostatic and bistatic systems, focusing of 3D data. 3. Processing of seismic refraction data: hints on acquisitions, first arrival picking, reciprocal methods, Generalized Reciprocal Method, tomographic inversion. 4. Processing of seismic reflection data: hints on acquisitions, gain, bandpass filters, FK filters, time-variant filters, velocity analysis, static and dynamic corrections, muting, residual statics, stack, deterministic and statistical deconvolution, pre-stack and post-stack multiple suppression, 2D and 3D migration, pre-stack migration, calibration with VSP data. 5. Processing of MASW data: Rayleigh waves, hints on acquisitions, spectral analysis through fk transform or tau-p transform, dispersion curve picking, inversion. 6. Tomographic inversion: hints on acquisitions, traveltime picking, time-calibration, inversion grid design, traveltime inversion, amplitude picking, divergence correction, radiation pattern correction, amplitude inversion, frequency downshift method. Laboratory: Part of the course consists of a large number of laboratory sessions with Matlab and with professional software for radar and seismic data processing.

 Prerequisiti
 Fundamentals of mathematics, differential equations, geometry and linear algebra.

 Modalità di valutazione
 Evaluation is based on an oral exam where the student might be asked to design a processing procedure or to discuss a specific data processing algorithm. The appointment for the exam is arranged upon request. Reserve your appointment with one week advance notice.
