Previously reported research examining the performance of higher-order correlation detectors for band Limited transient signals using hypothesis testing has been extended to include alternate detection methods, detector performance as a function of signal-to-noise ratios SNRs, and time-delay estimation. In particular, frequency-domain detection has been compared to detection in the time domain. Probability of detection is determined for example transients at a fixed false alarm rate over a domain of SNRs. The accuracy of time-delay estimation is investigated for these signals using high-order correlation estimators for the same noisy transients. Signals affected by the environment are also included in the analyses.
