The adaptive constant false alarm rate for sonar target detection based on back propagation neural network access

IET Signal Processing, 2023
With oceanic reverberation and a large amount of data being the main sources of interference for underwater acoustic target detection, it is difficult to obtain a more robust detection performance by relying on the traditional constant false alarm rate ...

From Detection to Countermeasure: A Review of Key Technologies in Counter‐Unmanned Aerial Vehicle Systems

IET Cyber-Systems and Robotics, Volume 8, Issue 1, January/December 2026.
ABSTRACT With the rapid proliferation of unmanned aerial vehicles (UAVs) in the military, logistics and public safety sectors, the threat of illegal intrusion, information theft, and security breaches has increased. This paper provides a comprehensive review of recent developments in counter‐unmanned aerial vehicle (counter‐UAV) systems, focussing on ...

A Novel Copula-Based Multi-Feature CFAR Framework for Radar Target Detection

Remote Sensing
Multi-feature radar target detection enhances the discrimination between targets and clutter, thereby improving detection accuracy. However, the complex nonlinear dependencies among features present significant challenges for precise control of the false

Robust Beamforming for ISAC Systems via Probability of Detection Optimisation

Electronics Letters, Volume 62, Issue 1, January/December 2026.
We propose a two‐step robust beamforming design for ISAC that maximises multi‐target detection probability while satisfying multi‐user SINR and per‐antenna power constraints. A sensing‐only Riemannian optimisation on the oblique manifold shapes the transmit covariance, followed by SDR‐based reconstruction to enforce communication guarantees ...

A constant false alarm rate (CFAR) detector for RADARSAT-2 along-track interferometry

Canadian Journal of Remote Sensing, 2005
Canada's RADARSAT-2 synthetic aperture radar (SAR) satellite will be equipped with an experimental ground moving target indication (GMTI) mode, which makes use of the "dual-receive" capability of the RADARSAT-2 antenna to provide two apertures aligned in the along-track direction.

Adaptive Multi‐Feature Validation Algorithm for Hovering UAV Detection via LFMCW Radar: Leveraging Micro‐Doppler Spectral Characteristics

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
The document proposes the micro‐Doppler spectral feature‐guided LFMCW radar detection algorithm (MDSF‐LRDA) to solve the high false alarm problem of detecting hovering rotor UAVs in cluttered environments, a limitation that plagues traditional radar methods relying on significant Doppler shifts.

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.

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)
