Canadian Journal of Remote SensingSpace-based polarimetric synthetic aperture radar (SAR) plays an important role in wide-area maritime surveillance and vessel detection. Traditionally, dual polarimetric (DP) SAR has been preferred for such applications, but compact polarimetric CP SAR is a newer option that potentially offers improved backscatter characterization of targets. There are

CFARnet: deep learning for target detection with constant false alarm rate [PDF]
, 2023 We consider the problem of target detection with a constant false alarm rate (CFAR). This constraint is crucial in many practical applications and is a standard requirement in classical composite hypothesis testing. In settings where classical approaches

IET Communications, Volume 20, Issue 1, January/December 2026.This paper presents a two‐stage genetic algorithm based waveform design framework for OFDM integrated sensing and communication (ISAC) systems. In Stage‐1, a multi‐objective genetic algorithm jointly optimizes the peak‐to‐average power ratio (PAPR) and peak sidelobe level ratio (PSLR) under forward error correction and reserved subcarrier constraints ...

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 ...

Acoustic tamper detection sensor with very low false alarm rate [PDF]
, 2008 We describe a device designed to detect interference (vandalism or tampering) by acoustic means. The design employs both a piezoelectric vibration transducer and a common microphone in a novel mechanical arrangement.

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 ...
