Aircraft location and tracking. High fidelity originalrecordings Typically, an array is made up of omnidirectional microphonesdistributed about the perimeter of a space, linked to a computer thatrecords and interprets the results into a coherent form. Arrays may alsobe formed using numbers of very closely spaced microphones. Given afixed physical relationship in space between the different individualmicrophone transducer array elements, simultaneous DSP ( Digital signalprocessor ) processing of the signals from each of the individualmicrophone array elements can create one or more 'virtual' microphones.…
