Abstract

Detection and bearing estimation of submerged vehicles through analysis of their broadband signals that may be 20 dB or lower than background noise is possible by measuring differential time of arrival (T) and differential time rate (T) or Doppler shift of the target signal received at a pair of DIFAR sonobuoys.
