Abstract
A simple yet effective statistic is proposed for detecting transient buried in partially unknown ambient noise. The transient model is the frequency scattered increased variance observations. We pose the transient detection problem as homogeneity test and the statistic is derived as the (generalized) likelihood ratio test of overdispersion when the underlying observation sequence follows a double exponential distribution. Numerical testing focuses on the comparison of this scheme with the CFAR power-law detector.
