Abstract
This Ph.D is concerned with wave propagation problems. The main focus is
on nonlinear acoustics, looking at sonic boom propagation in a physically realistic
atmosphere, whilst a secondary part will look at the problem of landmine detection
and how to improve the target detection rates.
The work on nonlinear acoustics emerged as a desire to model the behaviour
of the sonic booms formed by supersonic aircraft in the atmosphere to see what
environmental impact they would have on people and animals on the ground, in
terms of the form of the sound waves once they reach the ground.
The work on landmine detection originated from a Knowledge Transfer Partner-
ship between the University of East Anglia (UEA) and Cobham Technical Services
(CTS) organised through the Knowledge Transfer Network (KTN). This partnership
took the form of a six month internship with work undertaken afterwards to publish
the �ndings of the internship.
