IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.We propose a three‐element non‐uniform linear array (NULA) design strategy for OFDM‐based radar on a moving platform, optimizing multi‐channel DPCA processing with the T‐DPCA‐RF filter. Unlike heuristic approaches, our method constrains the DPCA filter response to avoid blind velocity effects within a target velocity range.

Une nouvelle décomposition tensorielle orthogonale, l'Alternative Unfolding HOSVD. Application au STAP Polarimétrique [PDF]
, 2013 National audienceDans cet article, on propose d'étendre les méthodes rang faible de traitement d'antenne à des cas multidimensionnelles. Deux types de méthodes peuvent être envisagés : l'approche vectorielle et l'approche tensorielle.

Intent Inference and Syntactic Tracking with GMTI Measurements
, 2011 In conventional target tracking systems, human operators use the estimated target tracks to make higher level inference of the target behaviour/intent. This paper develops syntactic filtering algorithms that assist human operators by extracting spatial ...

European Journal of Sport Science, Volume 24, Issue 12, Page 1788-1797, December 2024.Abstract The objectives of the study were (i) to evaluate the effects of whole‐body cryostimulation (WBC) after training as an effective tool to improve sleep and recovery and (ii) to determine which exposure schedule for WBC (immediately after training vs. 1h before bedtime) is the most appropriate to improve sleep and recovery.

Space-Time Adaptive Processing (STAP) Developments in Thales
, 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)
, 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
The 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 ...
