Deconvolution Methods and Systems for the Mapping of Acoustic Sources from Phased Microphone Arrays

NASA’s Langley Research Center researchers developed DAMAS using an iterative algorithm to deconvolute noise signals, allowing for more accurate quantification of the position and strength of acoustic sources. Recent development of the DAMAS microphone phased array processing methodology allows the determination and separation of coherent and incoherent noise source distributions. The DAMAS technology represents a significant breakthrough in the field of aero-acoustics.
