Knowledge of link specific traffic characteristics is important in the operation and design of wide area networks. Network tomography is a powerful method for measuring characteristics such as delay and loss on network-internal links using end--to--end active probes.

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 ...

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

Radar target imaging using distributed radar networks
2009 IEEE Antennas and Propagation Society International Symposium, 2009Target images can be clearly reconstructed from the monostatic and bistatic range profiles generated by a DRN with enough radar sensors. Because the images are instantly formulated, no synthetic aperture processing or motion compensation is needed.

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).

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.
