Problems in Nonlinear Acoustics: Parametric Receiving Arrays, Focused Finite Amplitude Sound, and Dispersive Nonlinear Interactions.

Abstract

Contract N00014-85-K-0708 provides for basic research on nonlinear acoustics. The three projects currently supported by the contract are as follows: 1) Use of a Parametric Receiving Array to Measure Ship Noise; 2) Focused Finite Amplitude Sound; and 3) Dispersive Nonlinear Wave Interactions in a Duct. The first project is the primary research effort supported by the contract, and the investigation is predominantly theoretical. The second involves computational analysis, the third experimental. Each project is discussed separately in the following sections. Keywords: Focused sound; Multipath; Hydrophones; Acoustic radiation.
