Acoustic Scoring and Locating System for Rockets, Artillery & Mortars

Acoustic sensors can be used to detect, classify and locate battlefield threats such as mortars, rifles and various vehicles. Sound pressure microphones are commonly used for this purpose, but this article focuses on Acoustic Vector Sensors (AVS’s). These sensors consist of three orthogonal particle velocity sensors in combination with a sound pressure microphone. These sensors make it possible to measure the direction-of-arrival of a sound wave instantaneously. The use of multiple sensors leads to very robust source localization and classification. This paper presents a system which consists of multiple Unattended Ground Sensors (UGS’s). Applications, with an emphasis on Acoustic Scoring and Locating System for Rockets, Artillery & Mortars (RAM-LOC), are discussed.
