Abstract: A sensor array includes a plurality of sensor locations at which sensed signals are produced. A tension element holds locations at a given maximum spacing. The tension element includes an optical fiber. Light propagating on the optical fiber is applied to converters at each location for generating electrical power for the electrically powered portions of the array. The electrically powered portions may be a part of the sensor suite at each location, telemetry equipment, or both.

Abstract: A system and process for localizing signals received on multiple co-linear arrays reduces the adverse effects on localization performance due to background noise. The system and process coherently combine all possible array cross-correlograms. The resulting correlogram is a function of two variables, one which corresponds to a fine bearing estimate and a second with maps into range.

Abstract: An energy beam-forming array of N+2 stations which utilizes a companion network of N optical sensors which mutually image each other to determine deviations of the optical sensors, and therefore the energy-receptive sensors, from a common linear axis. Each optical sensor measures the equivalent of a second-difference, which are then combined to reconstruct the actual array deviations. Each optical sensor is equipped with at least one pinpoint light source, to provide a light beam to an imaging subsystem provided at the next sensor station. The imaging subsystem includes a lens, either simple or compound, coupled to a retinal sensor array. The location of the light source image at the retinal array provides all of the necessary information for reconstruction of the array sensor location.
