Modeling of acoustic ground vehicle signatures and outdoor sound propagation

摘要

Forsvarets forskningsinstitutt (Norwegian Defence Research Establishment) is currently working on a program to develop improved models for both emission and propagation of acoustic waves from ground vehicles, to enable prediction of vehicle signatures as observed by remote sensors. The main purpose of this work in progress is to use such models as an aid to develop improved signal processing methods and pattern recognition algorithms for detection, classification and tracking of military vehicles with acoustic sensors.
