ACOUSTIC TOMOGRAPHY OF THE ATMOSPHERE USING ITERATED UNSCENTED KALMAN FILTER
Abstract: Tomography approaches are of great interests
because of their non-intrusive
nature and their ability to generate a
significantly larger amount of data in comparison
to the in-situ measurement method. Acoustic
tomography is an approach which
reconstructs the unknown parameters that affect
the propagation of acoustic rays
in a field of interest by studying the temporal
characteristics of the propagation.
Acoustic tomography has been used in several
different disciplines such as biomedical
imaging, oceanographic studies and atmospheric
The focus of this thesis is to study acoustic
tomography of the atmosphere in order
to reconstruct the temperature and wind velocity
fields in the atmospheric surface
layer using the travel-times collected from
several pairs of transmitter and receiver
sensors distributed in the field.
