Characteristics of the ARL:UT Moving Source Vertical Line Array Propagation Model (OBERON)

Abstract

This report describes a moving source vertical line array model based on normal mode theory. A stationary vertical line array consisting of omnidirectional receiver elements is insonified by a point time harmonic source moving with constant speed and direction. The acoustic field generated by the source is computed using normal mode theory with Doppler corrections. The computer model computes beam spectra and features array steering, shading, and Doppler effects such as line shifting and broadening. (Author)
