Broadband acoustic vector sensing in a forested environment

The horizontal acoustic particle velocity and acoustic pressure, concurrent with atmospheric data, were collected during a series of outdoor field tests. Here, we present the effects of a forested environment on acoustic vector sensing for broadband sources. The sources are representative of battlefield signals of interest. The complex distributions are studied in the unsaturated, partially saturated, and fully saturated regimes. Distinct path-dependent, frequency-dependent propagation effects are observed.
