Abstract: A class of planar arrays having broad frequency range applications for source location, source imaging or target illumination with projected beams is described in this disclosure. The non-redundant arrays are circularly symmetric and made up of a plurality of sensing and/or transmitting elements arranged so as to substantially eliminate grating lobes for a broad range of frequencies. Signals received from or transmitted to the elements are appropriately phased to control the beam of the array.

Abstract: A calibration device for calibrating a dynamic pressure sensor includes a power/control box and a portable calibration head disposed in electrical communication with the power/control box. The portable calibration head may include a calibration head housing having a housing opening and a speaker provided in the calibration head housing and communicating with the housing opening. The power/control box may be configured to induce emission of an acoustic calibration signal from the speaker of the calibration head.

Abstract: A system for an adaptable aperture planar array for maintaining source resolution is provided. The system includes a first nested array defining a first aperture responsive to a first range of frequencies. The first aperture is sized based on an angle between the array and the source, and includes a first subset of sensor elements. The system includes a second nested array defining a second aperture responsive to a second range of frequencies that is less than the first range of frequencies. The second aperture is sized based on the angle between the array and the source, and includes a second subset of sensor elements. The first aperture and second aperture change in size as the angle changes, which results in a change in the sensor elements within the first subset and the second subset to maintain the source resolution for the array.

Abstract: A multi-arm elliptic logarithmic spiral array that is particularly effective in off-axis beamforming applications. The array is formed by providing an elliptic logarithmic spiral and a plurality of concentric ellipses which intersect with angularly spaced apart sample points on the elliptic logarithmic spiral. An odd number of sample points are included on each ellipse. The array of the present invention is particularly effective in off-axis beamforming applications, such as aeroacoustic test applications within wind tunnels, where the location of the array is fixed and the source of noise is positioned off axis of the array.
