Abstract
Experimental work with three different adaptive processors has been carried out in order to study the problem of signal detection in a reverberation-limited environment. Single-channel real data as well as synthetic data have been used for the reverberation signals. Synthetic echoes and synthetic stepped FM pulses will be regarded as the contact signals to be detected.
Simulation results using an Adaptive Notch Filter (ANF), an Adaptive Noise Canceller (ANC) with its weights being adapted by means of the Least-Mean Square (LMS) algorithm, and an ANC in the form of a Least-Squares Lattice (LSL) filter, are presented.
It will be shown how the ANC by means of the LSL is capable of recovering even zero-Doppler echoes under certain signals conditions.
