Title: On the performance of an adaptation of Adichie's rank tests for signal detection and its relationship to the matched filter
Author: Brown, C.L.; Zoubir, A.M.; Boashash, B
Abstract: The Adichie rank test and signed rank test are adapted for signal detection. We establish a relationship with the correlation between a function of the signal to be detected and the ranks of the observed data. A comparison between the power of these tests and the constant false alarm rate matched filter (CFAR MF) shows that the rank tests perform better when longer observations are available and for the symmetric alpha stable distributions encountered in applications with impulsive interference.
Description: This paper shows that Adichie’s rank tests can be viewed as a correlator detector utilising rank information when exact distributional properties of the observed signal are unavailable. (Additional relevant material and details can be found in the comprehensive book on Time-Frequency Signal Analysis and Processing (see http://www.elsevier.com/locate/isbn/0080443354). In addition, the most recent upgrade of the original software package that calculates Time-Frequency Distributions and Instantaneous Frequency estimators can be downloaded from the web site: www.time-frequency.net. This was the first software developed in the field, and it was first released publicly in 1987 at the 1st ISSPA conference held in Brisbane, Australia, and then continuously updated).
