High-performance air acoustic detection and classification sensor
Richard Porter, Robert Raines, Barry Jones · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2009
Acoustic signals are a principal detection modality for unattended sensor systems. However, the performance of these systems is frequently suboptimal due to insufficient dynamic range in small systems or excess power consumption in larger systems. This paper discusses an approach to developing an unattended ground sensor (UGS) system that has the best features of both worlds. This system, developed by McQ Inc., has exceptional dynamic range (> 100 dB) while operating at power levels of 1.5-5 watts. The system also has a user definable signal parameter library and automated detection methodology that will be described.
