摘要： A method and system for enhancing a target sound signal from multiple sound signals is provided. An array of an arbitrary number of sound sensors positioned in an arbitrary configuration receives the sound signals from multiple disparate sources. The sound signals comprise the target sound signal from a target sound source, and ambient noise signals. A sound source localization unit, an adaptive beamforming unit, and a noise reduction unit are in operative communication with the array of sound sensors. The sound source localization unit estimates a spatial location of the target sound signal from the received sound signals. The adaptive beamforming unit performs adaptive beamforming by steering a directivity pattern of the array of sound sensors in a direction of the spatial location of the target sound signal, thereby enhancing the target sound signal and partially suppressing the ambient noise signals, which are further suppressed by the noise reduction unit.

摘要： The present invention is directed to provide an underwater detection system which can determine frequency components contained in echoes arriving from all azimuthal directions at high speed and enhance target discriminating capabilities by presenting such frequency components.The underwater detection system rotates a pair of ultrasonic receiving beams having a fixed phase angle difference, measures phase differences between two signals picked up by both ultrasonic receiving beams, determines carrier frequencies contained in target echoes from the phase differences, derives magnitudes and directions of moving velocities of targets from the carrier frequencies, and displays such target data in different colors. Furthermore, it provides such information as over-the-ground velocities of targets themselves upon compensating target velocity data with ship velocity data.

摘要： Systems, methods, tangible non-transitory computer-readable media, and devices associated with detecting and locating sounds are provided. For example, sound data associated with sounds can be received. The sounds can include source sounds and background sounds received by microphones. Based on the sound data, time differences can be determined. Each of the time differences can include a time difference between receipt of a source sound and receipt of a background sound at each of the microphones respectively. A set of the source sounds can be synchronized based on the time differences. An amplified source sound can be generated based on a combination of the synchronized set of the source sounds. A source location of the source sounds can be determined based on the amplified source sound. Based on the source location, control signals can be generated in order to change actions performed by an autonomous vehicle.
