Abstract The statistics of a class of transient signal detectors known as spectral correlative detectors (SCD) are investigated. Rather than use asymptotic statistics, which are not valid for the short sample sizes typically encountered in transient detection, finite sample statistics are developed. In particular, for the case of no frequency averaging, the statistics are characterized in terms of a magnitude-of-complex-Wishart (MOCW) density function, and a noncentral-MOCW (NMOCW) density function under the condition that the transient signal is absent and present, respectively. Subsequently, the statistics of the SCD for various coherent and incoherent averaging lengths are characterized in an analogous fashion. Finally some experimental verification of these densities is presented.
