Implementing Robust M-Estimators with Certifiable Factor Graph Optimization
Zhexin Xu, Hanna Jiamei Zhang, Helena Calatrava +2
Parameter estimation in robotics and computer vision faces formidable challenges from both outlier contamination and nonconvex optimization landscapes. While M-estimation addresses…
Label Hijacking in Track Consensus-Based Distributed Multi-Target Tracking
Helena Calatrava, Shuo Tang, Pau Closas
Distributed multi-target tracking (DMTT) in limited field-of-view (FoV) sensor networks commonly suffers from label inconsistency, whereby different nodes disagree on the identity…
Cooperative Differential GNSS Positioning: Estimators and Bounds
Helena Calatrava, Daniel Medina, Pau Closas
In Differential GNSS (DGNSS) positioning, differencing measurements between a user and a reference station suppresses common-mode errors but also introduces reference-station noise…
Advances in Anti-Deception Jamming Strategies for Radar Systems: A Survey
Helena Calatrava, Shuo Tang, Pau Closas
Deception jamming has long been a significant threat to radar systems, interfering with search, acquisition, and tracking by introducing false information that diverts attention fr…
Mitigation of Radar Range Deception Jamming Using Random Finite Sets
Helena Calatrava, Aanjhan Ranganathan, Tales Imbiriba +3
This paper presents a radar target tracking framework for addressing main-beam range deception jamming attacks using random finite sets (RFSs). Our system handles false alarms and…
On the Impact of Sampling on Deep Sequential State Estimation
Helena Calatrava, Ricardo Augusto Borsoi, Tales Imbiriba +1
State inference and parameter learning in sequential models can be successfully performed with approximation techniques that maximize the evidence lower bound to the marginal log-l…
Jammer classification with Federated Learning
Peng Wu, Helena Calatrava, Tales Imbiriba +1
Jamming signals can jeopardize the operation of GNSS receivers until denying its operation. Given their ubiquity, jamming mitigation and localization techniques are of crucial impo…
Recursive classification of satellite imaging time-series: An application to land cover mapping
Helena Calatrava, Bhavya Duvvuri, Haoqing Li +5
Despite the extensive body of literature focused on remote sensing applications for land cover mapping and the availability of high-resolution satellite imagery, methods for contin…
