Passive Acoustic Sensing Systems Engineering

Course Description

Get better acoustics. In the Battlefield Acoustics Signal Processing course, you will learn the basic physical principles underlying the propagation of acoustic signals in the atmosphere. These environmental factors influence sound near the ground and typical sources of noise that degrade the performance of acoustic signal processing systems. Discover techniques, such as hardware configuration and software algorithms, for designing acoustic systems for solving problems of interest in the battlefield.
