摘要： A system to extend transducer arrays from the hull of a vessel while it is underway provides for increased array gain, volumetric aperture (very large aperture arrays), and rejection of hull-bound noise for submarines, surface ships, weapons, and unmanned underwater and surface vehicles. A plurality of arms extend radially outwardly from the hull of a submarine, and passive and/or active elements of the arrays are mounted around the hull on the arms, trail in the water from the arms, or extend between different ones of the arms or between arms and the hull. The system of arms and the array are folded into elongate recesses in the hull to lower noise during higher speed transit by the submarine. The arrays can be made up of sensors and/or projectors of radar, sonar signals, optical energy, vibrational energy, magnetic influence, temperature, etc., and combinations of these sensors.

摘要： A system for analyzing a plurality of channels of data received from a sensor array. The system includes a data acquisition system that receives and independently processes each channel. A low-level processing section receives each channel of processed data and identifies signals of interest in one channel. Signals of interest are stored in an event database. A high-level processing section analyzes data occurring over a preset duration of time and across multiple channels of data and communicates with an operator machine interface. The operator machine interface provides analysis to an operator. Further aspects of the system characterize the data in order to indicate the data source and alert the operator to signals having certain predefined characteristics.

摘要： The present application discloses a method for resolving harmonic ambiguity and inter-array harmonic tracking. The method allows derivation of a complete set of possible harmonic families given the selection (by an operator) or automatic detection (by an automated algorithm) of a single tone (fselected) from a frequency spectrum using a novel “ambiguity matrix” approach in which a matrix of all N possible harmonic members and M hypothetical fundamentals is constructed. The ambiguity matrix provides an image of all possible harmonic families associated with a selected tone. The selection of the correct fundamental is then made based on simple comparisons between this image and the set of all possible fundamentals. The ambiguity matrix effectively provides a reduced finite solution space (discrete set of possibilities) in which to unambiguously estimate the correct fundamental.

摘要： A projectile trajectory and source location system and method identifies, calizes, and displays a projectile trajectory relative to one or more stationary objects, such as buildings in an urban environment. The system includes a sensor array and trajectory location calculator that sense conditions generated by the projectile, such as an acoustic signature, and calculate a set of ranges to the trajectory. A ranging system and range comparison calculator measure ranges to one or more stationary objects and compare those ranges to the set of ranges to the trajectory. A display displays the trajectory relative to the stationary objects including unobstructed portions of the trajectory, obstructed portions of the trajectory and the located source of the projectile. A tracking system and dynamic reprocessor track the movement of an observer, dynamically reprocess the relative trajectory location, and update the display of the relative trajectory location in response to the observer's movement.
