Transient signal detection in unknown colored noise fields
V. Nagesha, Steven Kay, John I. Salisbury · 1992
A generalized likelihood ratio test is described to detect a single transient signal in an unknown colored noise field using a line array. The transient signal is a one-sided exponential with known mode but unknown arrival angle and arrival time. Vast improvements over a conventional energy-based detector are possible and are attributed to prewhitening to account for the noise coloration.>
