Abstract :
Four-channel real reverberation signals recorded in shallow water are appropriately combined with zero-Doppler synthetic signals, regarded as the contact signals, to evaluate the performance of a least-squares lattice filter when applied to the detection of zero-Doppler contacts buried in reverberation, for different levels of input signal-to-reverberation ratio
