International Journal of Antennas and Propagation, 2015 We propose a new algorithm to suppress the jammer signals and estimate the direction of arrival (DOA) of the signal of interest (SOI) for collocated MIMO radar by using the matrix pencil method (MPM) and the generalized likelihood ratio test (GLRT).

Journal of Mathematics, Volume 2025, Issue 1, 2025.Influential analysis is the main diagnostic process to obtain reliable regression results. Same is true for the generalized linear model (GLM). The present article empirically compares the performance of different residuals of the gamma‐Pareto regression model (G‐PRM) to detect the influential points.

Subspace‐based distributed target detection method with small training data samples
IET Radar, Sonar &Navigation, Volume 18, Issue 12, Page 2541-2551, December 2024.Considering the improvement of radar resolution and some problems in the practical application of adaptive target detection, the target is modelled by subspace, and two detectors are proposed based on GLRT and Wald tests respectively. Finally, the CFAR theory analysis and performance simulation analysis of the detectors are carried out.

Generalized empirical likelihood estimators and tests under partial, weak and strong identification [PDF]
The principal purpose of this paper is to describe the performance of generalized empirical likelihood (GEL) methods for time series instrumental variable models specified by nonlinear moment restrictions when identification may be weak.

Knowledge-Aided Target Detection for Multistatic Passive Radar
IEEE Access, 2019 This paper studies the detection problem for multistatic passive radar. We consider scenarios where prior knowledge about the spectrum and peak-to-average ratio (PAR) of the non-cooperative illuminators of opportunity (IOs) is available.

A Modal-Domain Adaptive Subspace Detector in a Deep-Sea Environment
IEEE Access, 2019 In deep-sea environments, the conventional adaptive subspace detector (ASD) is realized in the hydrophone domain by applying the generalized likelihood ratio test (GLRT), in which acoustic signals lie in lower-dimensional modal subspaces. When the number

Generalized empirical likelihood tests in time series models with potential identification failure [PDF]
We introduce test statistics based on generalized empirical likelihood methods that can be used to test simple hypotheses involving the unknown parameter vector in moment condition time series models.

Generalized detector as a spectrum sensor in cognitive radio networks [PDF]
Radioengineering, 2015 The implementation of the generalized detector (GD) in cognitive radio (CR) systems allows us to improve the spectrum sensing performance in comparison with employment of the conventional detectors.

Optimal Comparison of Misspecified Moment Restriction Models under a Chosen Measure of Fit [PDF]
Suppose that the econometrician is interested in comparing two misspecified moment restriction models, where the comparison is performed in terms of some chosen measure of fit.
