Moving targets often appear defocused and displaced in SAR imagery, complicating detection and recognition—especially when displaced into cluttered regions, where signal‐to‐background ratio is reduced. This work presents a multistatic SAR framework that extracts moving target signatures and reconstructs focused images, providing new insights into the ...

Advances in Multistatic Sonar [PDF]
Although the concept of multistatic active sonar (MAS) has been around for over 50 years, new trends have brought this technology to the forefront of anti-submarine warfare research. These trends include advancements in sonar sensors and signal processing, advancements in submarine stealth, and a desire to track targets in noisy and reverberant ...

Range‐Free Localisation for Monostatic Passive Radar Employing Multi‐Narrowband Illuminators
Range‐free localisation is considered for monostatic passive radar with multiple narrowband illuminators under unreliable time‐delay (range) measurements. Doppler/DOA (and optional Doppler‐rate) are fused in an ML framework, where velocity is iteratively updated to reduce the original 6‐D optimisation to a 3‐D position search.

Characterisation and Classification of Resident Space Objects Using Radar Networks
This paper describes a simulated environment for generating Inverse Synthetic Aperture Radar (ISAR) images and interferometric point clouds using a three‐receiver radar configuration, along with the creation of extensive datasets to train and evaluate deep learning models under varying Signal‐to‐Noise Ratio (SNR) conditions. Findings show that modified
