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

The Engineering Research Center for Collaborative Adaptive Sensing of the Atmosphere (CASA) is investigating the use of dense networks of short-range radars for weather sensing. A first test-bed of this new paradigm is currently deployed in southwest Oklahoma.

Analysis of random radar networks
2008 42nd Asilomar Conference on Signals, Systems and Computers, 2008We introduce the notion of random radar networks to analyze the effect of geometry in distributed radar systems. We first analyze unistatic systems with a single receiver selected at random from the available group. We approximate the distribution of the individual signal-to-interference-plus-noise (SINR) at the sensors and find the corresponding mean ...

Network troubleshooting with SDN-RADAR
2015 IFIP/IEEE International Symposium on Integrated Network Management (IM), 2015Despite increasing deployment of software-defined networks (SDN), little is yet known about how to actually manage such kind of networks. When service degradation (generically termed here “trouble”) happens, the first step is to localise under-performing network paths (“troubleshooting”).

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 ...

Analysis of UWB Radar Sensor Networks
2010 IEEE International Conference on Communications, 2010Radar sensor networks (RSNs) are gaining importance in the context of passive localization and tracking. The performance of RSNs is affected by disturbances, system's parameters, network topology, and the number of radar elements. In this paper, we derive a unified analytical framework that takes all this aspects into account and allows the ...

Sensor Radar Networks for Indoor Tracking
IEEE Wireless Communications Letters, 2014Sensor radars (SRs) are important for a variety of applications requiring passive tracking of moving targets. The accuracy of passive tracking is severely degraded by wireless propagation impairments such as multipath, clutter, and non line-of-sight conditions, especially in indoor environments.

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

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).
