Modified Anderson-Darling Test-Based Target Detector in Non-Homogenous Environments
Sensors, 2014 A constant false alarm rate (CFAR) target detector in non-homogenous backgrounds is proposed. Based on K-sample Anderson-Darling (AD) tests, the method re-arranges the reference cells by merging homogenous sub-blocks surrounding the cell under test (CUT)

Electronics Letters, Volume 62, Issue 1, January/December 2026.To address the fragmentation of range‐spread targets in high‐resolution radar, we propose a fast, sparse vectorized clustering algorithm utilizing an anisotropic Chebyshev distance and an O(1) local grid block slicing technique. By mathematically decoupling the range and Doppler thresholds, our method intrinsically resolves the isotropic dilemma of ...

IET Image Processing, Volume 20, Issue 1, January/December 2026.Synthetic aperture radar (SAR) ship detection remains challenging due to inherent speckle noise, complex sea clutter, variable target scales, and arbitrary ship poses. This paper develops a YOLOv11‐based multi‐scale feature enhancement network, namely DWD‐Net, by integrating deformable convolution v4, a stochastic multi‐scale pooling attention ...

Proximate factors underpinning receiver responses to deceptive false alarm calls in wild tufted capuchin monkeys: is it counterdeception? [PDF]
, 2013 Previous research demonstrates that tufted capuchin monkeys use terrestrial predator alarm calls in a functionally deceptive manner to distract conspecifics when feeding on contestable resources, although the success of this tactic is limited because ...

Online Moving Interference Target Perception and Suppression for Passive Radar Detection of UAVs
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.An adaptive online prediction and suppression method for ground moving target interference based on an autoregressive model is proposed. The method performs regional partitioning and removal of ground interference targets by estimating and utilising the occurrence frequency of moving target interference.
