Abstract

A common problem in active sonar is that of multipath propagation in the ocean environment. A generalized likelihood ratio test (GLRT) approach is developed for detecting multiple target returns with unknown time delays and amplitudes in reverberation. The reverberation is modeled by a scattering function that is assumed to be described by the power spectral density of a complex autoregressive process. The generalized likelihood ratio test detector is described and its performance is compared to the clairvoyant optimal processor and an ad hoc processor.
