Abstract
The feasibility to perform B-scan imaging of buried objects in sediment by means of a parametric transmitter is investigated. The theoretical bases upon which the system is modeled are described. Numerical simulations are performed to estimate the expected lateral resolutions and the available acoustic levels. The influence of the main parameters is analyzed: diameter and altitude of the projector, primary frequencies and frequency ratio of primary-to-secondary fields. The optimal configurations are searched. A comparison with equivalent linear systems is presented.
