Proceedings of the 4th ACM SIGCOMM conference on Internet measurement, 2004
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.

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

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

Power Control Game Between a Distributed Radar Network and a Smart Jammer
IEEE Systems JournalIn this article, the game theoretic power control for a distributed radar network in the presence of a smart jammer is investigated. The main objective of the radar network is to minimize its total transmit power while maintaining desirable estimation ...

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.
