Second-Order Characterization of Micro Doppler Radar Signatures of Drone Swarms Open
We investigate the second-order characteristics of the radar return signal from a swarm of rotor drones. We consider the case of a swarm of identical drones, with each a number of rotors comprised of a number of rotor blades. By considerin…

Modeling electrical distribution networks with inhomogeneous Galton-Watson trees Open
In this paper we consider inhomogeneous Galton-Watson trees, and derive various moments for such processes: the number of vertices, the number of leaves, and the height of the tree. Also we make a simple condition of finiteness. We use the…

Distributed Algorithm for Cooperative Joint Localization and Tracking Using Multiple-Input Multiple-Output Radars Open
We propose a distributed joint localization and tracking algorithm using a message passing framework, for multiple-input multiple-output radars. We employ the mean field approach to derive an iterative algorithm. The obtained algorithm fea…

Variational Message Passing-based Multiobject Tracking for MIMO-Radars using Raw Sensor Signals Open
In this paper, we propose a direct multiobject tracking (MOT) approach for MIMO-radar signals that operates on raw sensor data via variational message passing (VMP). Unlike classical track-before-detect (TBD) methods, which often rely on s…

Selection of measurements for state estimation in electrical power distribution grids Open
The electrical state of the power distribution grid can be estimated based on noisy measurements of a subset of voltages and currents in the grid. The accuracy and cost of such state estimation depends strongly on the selection of measuran…
