Abstract: Systems and methods are disclosed for autonomous joint detection-classification of acoustic sources of interest. Localization and tracking from unmanned marine vehicles are also described. Based on receiving acoustic signals originating above or below the surface, a processor can process the acoustic signals to determine the target of interest associated with the acoustic signal. The methods and systems autonomously and jointly detect and classify a target of interest. A target track can be generated corresponding to the locations of the detected target of interest. A classifier can be used representing spectral characteristics of a target of interest.

Abstract: Systems and methods are disclosed, which include or present “soundscapes” in or for online mapping utilities. To obtain the data for such soundscapes, along with cameras for visual images, a microphone array can be mounted on a vehicle to record sounds along the streets travelled for linking to an online map. A speech recognition algorithm is used to identify private conversations and remove them from the recording. The systems and methods for accomplishing this task include use of an array of microphones mounted in a special pattern with special materials on top of the vehicle to record sounds as the vehicle travels through space and time. A set of signal processing algorithms is also used to process the microphone signals autonomously in real-time, allowing the operator to immediately review them for quality assurance.

Abstract: A method of and system for monitoring the acoustic transmission conditions in underwater areas using an unmanned, mobile, submersible vehicle of the type including a source of acoustic signals. The submersible vehicle is controlled so that the vehicle traverses a desired path through the water of an area of interest. As the submersible vehicle traverses the desired path, a time-synchronized acoustic signal is transmitted from the acoustic source to at least one receiver spaced from the submersible vehicle so as to generate data representing the acoustic properties of the environment in the water between the acoustic source and the at least one receiver as the submersible vehicle traverses the desired path.
