Graph‐Based Spectrum Sensing via Quadratic Form of Adjacency Matrix
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This graphical abstract presents a graph‐signal‐processing‐based spectrum sensing algorithm for robust primary user detection at low signal‐to‐noise ratios (SNR). The observed signal is preprocessed via power spectrum calculation and block summation, and then transformed into a graph.

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 ...

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

Hypothesis testing and decision making: Constant-false-alarm-rate detection
, 2009 Detection is the first task in establishing a communication link, or tracking a target with a radar system. This is a decision-making problem, and it is performed through a hypothesis-testing procedure.

GNSS Spoofing Detection Based on Ionospheric Model Deviation Monitoring
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.The deviation of TEC (DTEC) consistency between DF measurements and empirical model estimations in authentic scenarios is not zero but is predictable through ionospheric annual periodicity. However, DF spoofers typically struggle to accurately counterfeit the authentic TEC value, which can disrupt the consistency between DTEC measurements and ...

Improving Of IS-CFAR Using Wavelet De-Noising For Smoothing The Noise In Reference Cells
Journal of Engineering and Sustainable Development, 2014 Constant false alarm rate (CFAR) algorithms allow RADAR systems to set detection thresholds and isolated the target from noise or clutter to keeping the false alarm rate at certain level.

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.Traditional ambiguity resolution methods relying on local decision mechanisms and idealised numerical rules are prone to performance degradation in complex scenarios characterised by low SNR and dense residual clutter. To address this limitation, this paper proposes a physics‐guided spatio‐temporal transformer (PG‐STT) algorithm, where physically ...
