Comments on “Statistical Analysis of the Nonhomogeneity Detector for Non-Gaussian Interference Backgrounds”

摘要

Rangaswamy [“Statistical Analysis of the Nonhomogeneity Detector for Non-Gaussian Interference Backgrounds,” IEEE Trans. Signal Process., vol. 53, no. 6, pp. 2101–2111, Jun. 2005] presented a statistical analysis with respect to the nonhomogeneity detector (NHD) for non–Gaussian interference scenarios. However, except for one case, Rangaswamy did not provide explicit expressions for the statistical quantities of interest. In this Comment, exact and elementary expressions are derived for all of the quantities considered by the statistical analysis.
