Motivated by the recurring use of the generalized Gaussian family to model different underwater noise sources and the asymptotic performance levels of some commonly used detectors for this family, we examined the performance of these detectors for this family, we examined the performance of these detectors for several different underwater noise sources. The sources considered are non-Gaussian, highly correlated, generally nonstationary, and vary from being lighter to heavier tailed than Gaussian. Although the linear detector had the best performance, the linear rank detector and the L-level uniform quantizer consistently had similar performance levels. Considering the simplicity and the robustness of the quantizer and the rank detectors, either of these detectors would seem to be the best choice for these environments.
