051270 - SUBSURFACE IMAGING AND DETECTION
The course presents a remote sensing approach for the imaging of the subsurface and the identification of specific targets. Different geophysical methods are studied from the basic principles up to the data collection and processing. The common framework is the generation and recording of a non destructive analysis signal (acoustic, elastic, electromagnetic) that propagates within the medium, collecting information about its properties. Particular attention is posed on the identification of the observable parameters, on the resolution and reliability of the final image, on the potentiality of multi domain data integration.
The course shows also current case histories and applications (identification of contaminant plumes, pipeline integrity monitoring, exploration for fluids, rescue of survivors under ruins, automatic tracking of acoustic sources).
Risultati di apprendimento attesi
The students will be able to
D1. Knowledge and understanding.
have an extended and multidisciplinary view on the remote sensing techniques and possibilities
understand the physics behind each sounding method
D2. Applying knowledge and understanding.
use specialized SW to simulate the "sounding" in a synthetic scenario (e.g. the elastic wave propagation in a layered medium) and to understand “experimentally” the theoretical principles
participate and collaborate in geophysical field campaigns
D3. Making judgements.
for a given scenario, infer the sounding methods applicability
for a given sounding method, define pros and limits.
prepare and present a report of a geophysical imaging campaign, also with field campaigns and homeworks
D5. Lifelong learning skills
describe and parameterize a problem
design a solution flow chart
- Remote sensing framework
Source, receiver and analysis signal. Observability and resolution.
Model space and data space: direct and inverse relations.
The course presents geophysical methods which are able to detect and monitor subsurface contamination. In particular, the electrical method is used for water exploration and classification (SDG6). These topics are presented and analyzed for about 10 hours.
Moreover, geophysical remote sensing principles sustain the industry innovation (SDG9). Examples are given (2-4 hours), in the field of pipeline fluids transportation, of innovative integrity monitoring system and techniques, based on vibroacosutic data collection and processing.
Introductory courses in signal processing and mathematics.
Modalità di valutazione
During the course, the students are asked to use simulation SW of subsurface images construction, and to produce running examples. At the exam the students, individually, present and run the examples, collocating them in the general framework of the remote sensing techniques, and explaining the underlying physical principle.
The exam is oral and it is graded between 0 and 30 "cum laude".
