Space-Time Adaptive Processing (STAP) Developments in Thales

open access: yes, 2009
Space-Time Adaptive Processing (STAP) has been shown to provide significant improvements in many different application areas [1]. Though similar in principle, those applications exhibit specificities, related for example to the characteristics of the antenna arrays and to the statistical properties of the involved signals.

Robust Covariance Matrix Estimation for Radar Space-Time Adaptive Processing (STAP)

open access: yes, 2016
Estimating the disturbance or clutter covariance is a centrally important problem in radar space time adaptive processing (STAP). The disturbance covariance matrix should be inferred from training sample observations in practice. Large number of homogeneous training samples are generally not available because of difficulty of guaranteeing target free ...

Three-dimensional sparse recovery space-time adaptive processing for airborne radar

open access: yesThe Journal of Engineering, 2019
Conventional 3-dimensional (3D) space-time adaptive processing (STAP) has achieved good performance for non-stationary clutter suppression. However, the performance of 3D STAP rapidly degrades when applied to heterogeneous clutter environment due to the ...

Reduced rank interference suppression for multichannel SAR [PDF]

open access: yes, 2006
Large regions of a Synthetic Aperture Radar (SAR) image can potentially be destroyed by an airborne broadband jammer. Jammer components include both the direct-path and multipath reflections from the ground, known as hot-clutter (HC) or terrain scattered

Sparsity-Based Non-Stationary Clutter Suppression Technique for Airborne Radar

open access: yesIEEE Access, 2018
Conventional space-time adaptive processing (STAP) technique can achieve perfect performance when applied to side-looking airborne radar (SLAR), where the clutter is relatively stationary, whereas it suffers significant degradation for non-SLAR due to ...

Sea Clutter Suppression by Atomic Norm Minimisation in Frequency Diverse Array‐Space‐Time Adaptive Processing Radar Under Range Ambiguity

open access: yesIET Radar, Sonar & Navigation
Sea clutter suppression is a hot topic for airborne radar. Space‐time adaptive processing (STAP) is a useful approach to address this issue. Currently, range ambiguity is a problem to restrict conventional STAP performance.

Estimation par Maximum de Vraisemblance du sous espace clutter dans un bruit hétérogène rang faible avec application au STAP [PDF]

open access: yes, 2013
National audienceDans le contexte d'une cible noyée dans un clutter hétérogène de rang faible plus un bruit blanc gaussien, les méthodes de filtrage rang faible requièrent moins de données secondaires que les méthodes classiques pour atteindre des ...
