Adaptive Beamforming for Sonar Signal Processing [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1966
The detection of weak sonar signals in a system exhibiting interchannel noise correlation may be enhanced by a beam-forming technique first introduced hy Mermoz, which maximizes the output signal-to-noise ratio. Such a system has been implemented, using an analog computer, for the case of two input channels.

Cyclostationarity Based Sonar Signal Processing

open access: yesProcedia Computer Science, 2016
AbstractThis paper presents a reliable method for target vessel identification in passive sonar by exploiting the underlying periodicity of propeller noise signal, using the principles of cyclostationarity. In conventional signal processing methods, random signals are treated as statistically stationary and the parameters of the underlying physical ...
