sonar and spatial audio -凯发官方首页

simulate an active monostatic sonar scenario with two targets. the sonar system consists of an isotropic projector array and a single hydrophone element. the projector array is spherical in shape. the backscattered signals are received by the hydrophone. the received signals include both direct and multipath contributions.

simulate a passive sonar system. a stationary underwater acoustic beacon is detected and localized by a towed passive array in a shallow-water channel. the acoustic beacon transmits a 10 millisecond pulse at 37.5 kilohertz every second, and is modeled as an isotropic projector. the locator system tows a passive array beneath the surface, which is modeled as a uniform linear array. once the acoustic beacon signal is detected, a direction of arrival estimator is used to locate the beacon.
