Acoustic signals from an acoustic event are captured via sensing nodes of sensor group(s) that comprise a group of sensing nodes at a location comprising spatial boundaries. Each of the sensing nodes comprise a sensor area. Each of the sensor group(s) is based on: range limits of each of the sensing nodes; shared sensing areas of the sensing nodes; and intersections between the sensor area for each of the sensing nodes and the spatial boundaries. Solutions(s) are generated by processing the acoustic signals. The solution(s) indicate the location of the acoustic event. A strength of solution compliance value for at least one of the solution(s) is determined. A refined solution is generated employing: sensor contributions of sensing nodes; and the strength of solution compliance value with the spatial boundaries and at least one of the solution(s). A report is created comprising the location of the acoustic event.

Device for acoustic source localization

A first plate comprises a first lip, lip gaps, and first indexing formations. The first lip extends around a portion of the first plate. The lip gaps are distributed along the first lip. The first indexing formations are distributed along the first lip between lip gaps. A second plate comprises mounting points, a second lip, mounting tabs, and second indexing formations. The mounting points may receive mounting fasteners to secure the second plate to an object. The second lip extends around a portion of the second plate. The mounting tabs are distributed along the second lip and positioned to align with lip gaps. The second indexing formations are disposed on mounting tabs to engage first indexing formations in response to the second plate having mounting tabs inserted through lip gaps and rotated until at least one first indexing formation is aligned with at least one second indexing tab.

Adjustable mounting system

The sensor group(s) comprise a group of sensing nodes at a location. The location comprises spatial boundaries. Each of the sensing nodes comprise a sensor area. Each of the sensor group(s) based on: range limits of each of the sensing nodes; shared sensing areas of the sensing nodes; and intersections between the sensor area for each of the sensing nodes and the spatial boundaries. Acoustic signals are captured from an acoustic event via sensing nodes of sensor group(s). Solution(s) are generated by processing the acoustic signals. The solution(s) indicate the location of the acoustic event. A strength of solution compliance value is determined for solution(s). A refined solution is generated employing: sensor contributions of sensing nodes; and the strength of solution compliance value with the spatial boundaries and solution(s). A report comprising the location of the acoustic event is transmitted.

System for confined spaces acoustic source localization

The source of an acoustic even is located. Spatial boundaries for a location are determined. Sensing nodes are placed at the location. The intersection between a sensor area for sensing nodes and spatial boundaries is found. Sensor group(s) of sensing node(s) are determined, based at least in part, on sensing node range limits and shared sensing areas. Solution(s) are generated by processing acoustic event detections based on a multi-sensor fusion of sensor group(s). Solution(s) are refined employing sensor contributions based on a strength of solution compliance value with the spatial boundaries and advancing optimal solutions. Solution(s) are routed to a hub for integration with other services.

Acoustic source localization in confined spaces

An electro-optic system, e.g., mounted to a weapon, measures down range winds and a range-to-target for compensating the ballistic hit point. The system may include an optical light source, collimated to generate a laser spot on the target. The system may include a wind measurement receiver that captures laser light scattered from the target. The captured light may be modulated by atmospheric scintillation eddies, producing optical patterns which change in time and move with the crosswind. These patterns may be analyzed by a processor using covariance techniques in either the time-domain or the frequency-domain to determine path-integrated crosswinds and associated errors. Ranging is done by measuring the time of flight of the laser pulse to the target collecting the scattered signal from the target. Compensated ballistic hit point, measurement errors and other data may be displayed on a micro-display digital eyepiece, or projected onto the direct view optics (DVO) of a riflescope so as to be overlaid in real-time on the optical image of the target.
