Abstract:

Numerical results are presented for a planar thin dome model showing how the dome influences the parametric generation efficiency at steering angles of 0, 20, and 45 deg. An extension of the model to the thick dome case is also included. During the next quarter, a comparison will be made between the thick and thin dome cases in order to develop a more quantitative criterion for judging whether a dome is acoustically thin for the higher primary frequencies of a parametric sonar.
