FMCW Radar Network: Multiple Access and Interference Mitigation
IEEE Journal on Selected Topics in Signal Processing, 2021With the increasing proliferation of radars on vehicles, interference among vehicular radars is becoming a serious issue. In this work, we consider a frequency modulated continuous wave (FMCW) radar network with coherent radar interference where all ...

Pedestrian Trajectory based Calibration for Multi-Radar Network
Conference on Computer Communications Workshops, 2021In recent years, using radio frequency (RF) signal for pedestrian localization and tracking has aroused great interest of researchers due to its property of privacy protection. With the high spatial resolution, millimeter wave (mmWave) becomes one of the

Microwave Photonics for a Radar Network
OSA Advanced Photonics Congress (AP) 2019 (IPR, Networks, NOMA, SPPCom, PVLED), 2019The benefits of photonics-based fully coherent radar networks are analyzed. The first photonics-based coherent 2×2 MIMO radar network has been implemented and tested in real environments confirming the potential of photonics in overcoming RF issues.

2007 Conference Record of the Forty-First Asilomar Conference on Signals, Systems and Computers, 2007
In this paper the coverage performance of a radar network is examined in which four different forms of processing concept are applied to the same data collected. It is found that the coverage performance can be strongly dependent on the form of the processing concept used and on the number of the nodes (for a given false alarm rate).

SPIE Proceedings, 2013
The potential applicability of multiple-channel coherence estimation in situations where one channel contains a noise-free signal replica (as in active radar) or a high-SNR reference signal (as in passive coherent radar) has been proposed in recent work.

Radar network characterization
2007 IEEE International Geoscience and Remote Sensing Symposium, 2007The use of dense networks of small radars for weather sensing is being investigated by the Engineering Research Center for Collaborative Adaptive Sensing of the Atmosphere, with a first test-bed of this new paradigm well underway. The potential benefits of closely-deployed, overlapping, short-range weather radars are easy to see intuitively, and can be

Applied Optics, 1994
A laser radar whose resolution is greater than 1 µm is reported. We present the radar results when they are used for such purposes as determining the size of a void inside a silicon wafer, profiling a cross-sectional pattern of an optical fiber, studying the birefringence of a lithium-niobate crystal, or finding a fault in an optical guide in an ...

Informative Radar Selection for Tracking in Radar Networks
IET International Radar Conference 2015, 2015In radar networks, radar selection has played a more and more important role. Many radar selection methods have been proposed. Recently a novel method which is based on sparsity-aware matrix decomposition has been proposed to identify informative sensors for target tracking. However, this method had stringent constraints and was under the assumption of
