Abstract
Some primary objectives of research and development for battlefield acoustic sensing include the optimization of sensors, arrays, and signal processing algorithms for the detection, localization, and classification of diverse broadband and transient threats in complex environments. Time-difference-of-arrival and frequency domain signal processing techniques using distributed microphone arrays allow sound source localization and tracking through triangulation in the 3-D space. This presentation will introduce general applications of broadband acoustic and infrasonic microphone arrays, acoustic particle velocity sensors, geophones, propagation environment effects and wind mitigation methods.
