We describe the use of radar beam-park experiments to characterize the space debris resulting from a recent fragmentation event, the deliberate demolition of the defunct Kosmos-1408 satellite. We identify the Kosmos-1408 fragments and present distribution of measurement parameters as well as proxy orbit parameters. We present and apply a novel tech...
Analysis of EM waves from both the scattering model and hardware sides has grown exponentially since the requirements of electrical devices have become stricter in order to serve various applications. High performance computing based EM emulators are used to simulate real-time complex EM wave interactions between multiple radar targets, transmitter...

Multi-class road user detection using the next- generation, 3+1D (range, azimuth, elevation, and Doppler) radars has been shown feasible, thanks to the increased density of their point clouds and the inclusion of elevation information. However, object detection networks using LiDAR (64-layer) point clouds still dominate the performance metrics. In ...
Le sujet de la thèse est la poursuite de plusieurs cibles, qui évoluent de manière indépendante, à partir de mesures recueillies par des capteurs ponctuels ou sous la forme d’une image-radar. Les algorithmes étudiés entrent dans la catégorie des filtres particulaires. Dans une première partie, on compare deux algorithmes proposés dans la littératur...
Dual-Functional Radar-Communication systems enhance the benefits of communications and radar sensing by jointly implementing these on the same hardware platform and using the common RF resources. An important and latest concern to be addressed in designing such Dual-Functional Radar-Communication systems is maximizing the energy-efficiency. In this...
Clouds are critical to the majority of aspects of human existence on earth. They also have a significant impact on the earth's energy balance. Although the effect of clouds on the climate is complex and not fully understood, much of the uncertainty about global warming is related to the cloud-climate feedback problem. Studies have shown that the re...
