Abstract
A computing device is provided, comprising a processor configured to receive a set of measurements of a vector x of acoustic data, including noise, interference, and a signal of interest. The processor may express x in a frequency domain discretized in a plurality of intervals. For each interval, the processor may generate an estimate Ŝof a covariance matrix of x. For each Ŝ, the processor may use acoustic imaging to obtain an estimate Ŷ of a spatial source distribution. For each Ŷ, the processor may remove the signal of interest to produce an estimate Ŵ of a noise and interference spatial source distribution. For each Ŵ, the processor may generate an estimate Ŝof a noise and interference covariance matrix. The processor may generate a beamformer configured to remove noise and interference from the acoustic data, wherein the noise and interference at each frequency are identified using Ŝ.
