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.

Fourth IEEE Workshop on Sensor Array and Multichannel Processing, 2006., 2006
This paper describes the use of cognitive radar networks for the reliable surveillance of an environment where the likelihood of the presence of uncooperative targets is high. Despite the limited effectiveness of amplitude as a radar discriminant, through the clever use of detection through tracking, the detection performance of the noncoherent radar ...

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

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.

In this chapter, we discuss the advantages of exploiting photonic techniques in radar networks. More in detail, we first review the specific requirements of radar networks, focusing in particular on the coherence requested to the radar signals at the different network nodes.

Radar selection for single-target tracking in radar networks
2015 IEEE Radar Conference (RadarCon), 2015A sensor networks comprise a large number of sensor nodes collaboratively collecting information, carrying out simple computation with their onboard processing capabilities. In recent years, sensor selection has become an important problem in managing sensor networks.

RADAR 2002, 2002
The networked radar air picture is built using input from radars in many different locations. In an ideal world, each radar can track every target continuously. However, the laws of physics do not permit this. Target fades, terrain blockage, and spurious signals all conspire to make the situation not ideal. As a result, in general, no one radar is able

Compressed sensing radar surveillance networks
2012 IEEE 7th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2012We study the problem of sensor fusion in a simplified radar surveillance application. A potentially large number of narrowband radars with isotropic antennas monitor a two-dimensional area for an unknown number of targets. We use techniques from compressive sensing to distribute efficient projections of network observations, allowing for reconstruction
