Cramér-Rao Bound Optimization for Joint Radar-Communication Beamforming [PDF]

open access: yesIEEE Transactions on Signal Processing, 2021
In this paper, we propose multi-input multi-output (MIMO) beamforming designs towards joint radar sensing and multi-user communications. We employ the Cramér-Rao bound (CRB) as a performance metric of target estimation, under both point and extended ...

An Overview of Signal Processing Techniques for Joint Communication and Radar Sensing [PDF]

open access: yesIEEE Journal on Selected Topics in Signal Processing, 2021
Joint communication and radar sensing (JCR) represents an emerging research field aiming to integrate the above two functionalities into a single system, by sharing the majority of hardware, signal processing modules and, in a typical case, the ...

Quantum Radar [PDF]

open access: yesPhysical Review Letters, 2020
We propose a quantum metrology protocol for the localization of a non-cooperative point-like target in three-dimensional space, by illuminating it with electromagnetic waves. It employs all the spatial degrees of freedom of N entangled photons to achieve an uncertainty in localization that is sqrt(N) times smaller for each spatial direction than what ...

Joint Radar and Communication Design: Applications, State-of-the-Art, and the Road Ahead [PDF]

open access: yesIEEE Transactions on Communications, 2019
Sharing of the frequency bands between radar and communication systems has attracted substantial attention, as it can avoid under-utilization of otherwise permanently allocated spectral resources, thus improving efficiency.

Multi-class Road User Detection with 3+1D Radar in the View-of-Delft Dataset

open access: yesIEEE Robotics and Automation Letters, 2022
Next-generation automotive radars provide elevation data in addition to range-, azimuth- and Doppler velocity. In this experimental study, we apply a state-of-the-art object detector (PointPillars), previously used for LiDAR 3D data, to such 3+1D radar ...
