PROBLEM TO BE SOLVED: To provide a noise source decomposition system and method using an adaptable aperture phased array.SOLUTION: A first array 102 of microphones is mounted on a platform moveable from a starting position to an ending position along a line parallel to a central axis of a noise source 101. A second array 103 of microphones includes sound sensors mounted on a separated fixed position with respect to the noise source. A processing system 104 processes first information from the first array of microphones, and second information from the second array of microphones. The processing system collects and stores the first and second information at each discrete step of the first array, spatially filters the first information, processes and calibrates the filtered first information on the basis of the second information, and further processes the calibrated first information to obtain a characteristic at a selected location. |
