A Prototype Acoustic Battlefield Decision Aid Incorporating Atmospheric Effects and Arbitrary Sensor Layouts

The Acoustic Battlefield Aid (ABFA) is a prototype decision aid for assessing the performance of acoustic sensors in different environments. ABFA combines accurate modeling of atmospheric effects on acoustic signals with newly developed methods for determining acoustic array performance. The report describes the methods by which ABFA calculates such quantities as transmission loss, signal-to-noise ratio, detection probability, array direction-finding accuracy, and position-finding accuracy from array networks. Some example calculations are provided for propagation over rough terrain in various weather conditions.Army Research Lab Adelphi is the author of 'A Prototype Acoustic Battlefield Decision Aid Incorporating Atmospheric Effects and Arbitrary Sensor Layouts' with ISBN 9781423558460 and ISBN 1423558464.
