Adaptive CUSUM Chart for Simultaneous Monitoring of Mean and Variance
Quality and Reliability Engineering International, Volume 42, Issue 5, Page 2150-2164, July 2026.ABSTRACT Simultaneously monitoring changes in both the mean and variance is a fundamental problem in statistical process control, and numerous methods have been developed to address it. However, many existing approaches face notable limitations: Some rely on tuning parameters that can significantly affect performance; others are biased toward detecting

Matched direction detectors and estimators for array processing with subspace steering vector uncertainties [PDF]
, 2005 In this paper, we consider the problem of estimating and detecting a signal whose associated spatial signature is known to lie in a given linear subspace but whose coordinates in this subspace are otherwise unknown, in the presence of subspace ...

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

Omnibus goodness‐of‐fit tests for univariate continuous distributions based on trigonometric moments
Statistica Neerlandica, Volume 80, Issue 2, May 2026.ABSTRACT We propose a new omnibus goodness‐of‐fit test based on trigonometric moments of probability‐integral‐transformed data. The test builds on the framework of the LK test introduced by Langholz and Kronmal [J. Amer. Statist. Assoc. 86 (1991), 1077–1084], but fully exploits the covariance structure of the associated trigonometric statistics.

Detection of Unknown Radar Pulses Using Spiking Neural Networks
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This article proposes to use spiking neural networks (SNNs) to detect multiple pulses in observation windows from a superheterodyne receiver. The method is described from encoding to postprocessing. New metrics are introduced to compare the proposed detection method to the energy detector (ED), to a detection based on difference Of boxes (DOB) filters ...

Matched subspace detection with hypothesis dependent noise power [PDF]
, 2008 We consider the problem of detecting a subspace signal in white Gaussian noise when the noise power may be different under the null hypothesis—where it is assumed to be known—and the alternative hypothesis.

MIMO Radar Detection Algorithms With Location Capabilities for Heterogeneous Environments
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.The design of adaptive detection and localisation algorithms in the context of MIMO radars is still an untraveled research route. In this paper, we present new decision schemes for MIMO radars capable of estimating, as a byproduct, the scatterer positions within the range‐Doppler bin under test and that can operate in both homogeneous and heterogeneous
