The development and testing of a parametric SONAR system for use in sediment classification and the detection of buried objects

posted on 2018-05-15, 11:27 authored by Paul A. LepperThis thesis describes the work carried out in the development and testing of
parametric sonar systems for application in the fields of seabed sediment
characterisation and classification, and the detection of seabed embedded objects.
Parametric sonar systems offer a number of advantages over conventional sonar
systems. This is especially true of the conflicting requirements of both seabed
delineation and penetration required for a practical sub-seabed profiling system.
Echoes from sub-bottom layers vary in strength dependent on both the boundary
acoustic reflectivity and the absorption characteristics of the layer above.
Absorption effects are usually frequency dependent, allowing better penetration to
lower frequency signals. [Continues.]
