Generalised RAO test for polarimetric target detection [PDF]
The Journal of Engineering, 2019 Here, a generalised Rao test method is presented for polarimetric multichannel adaptive signal detection. By introducing several tunable parameters into the Rao test detection statistics, the proposed polarimetric detector is quite general with the ...

Rao and Wald Tests for Nonhomogeneous Scenarios [PDF]
Sensors, 2012 In this paper, we focus on the design of adaptive receivers for nonhomogeneous scenarios. More precisely, at the design stage we assume a mismatch between the covariance matrix of the noise in the cell under test and that of secondary data.

A Robust Generalization of the Rao Test [PDF]
Journal of Business & Economic Statistics, 2021 This article presents new families of Rao-type test statistics based on the minimum density power divergence estimators which provide robust generalizations for testing simple and composite null hypotheses. The asymptotic null distributions of the proposed tests are obtained and their robustness properties are also theoretically studied.

Complex Parameter Rao and Wald Tests for Assessing the Bandedness of a Complex-Valued Covariance Matrix [PDF]
SignalsBanding the inverse of a covariance matrix has become a popular technique for estimating a covariance matrix from a limited number of samples. It is of interest to provide criteria to determine if a matrix is bandable, as well as to test the bandedness ...

Statistical Resolution Limit Analysis of Two Closely Spaced Signal Sources Using Rao Test
IEEE Access, 2017 High computational complexity and difficulty in taking an analytical expression of detection statistics are some of the problems encountered when using the statistical resolution limit (SRL) analysis in the generalized likelihood ratio test (GLRT). A Rao

Rao and Wald Tests in Nonzero-Mean Non–Gaussian Sea Clutter [PDF]
Remote SensingThe non-Gaussian nature of radar-observed clutter echoes induces performance degradation in the context of remote sensing target detection when using conventional Gaussian detectors. To enhance target detection performance, this study addresses the issue

Rao and Wald Tests for Moving Target Detection in Forward Scatter Radar [PDF]
Remote SensingThis paper deals with adaptive moving target detection for a forward scatter radar in complex Gaussian noise. The echoes received by the forward scatter radar include not only the noise and the possible target signals but also the direct signals.
