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.

2007 IEEE International Geoscience and Remote Sensing Symposium, 2007
A network-based reflectivity retrieval technique has been developed within the Center for Collaborative Adaptive Sensing of the Atmosphere (CASA). The concept of a networked- radar system is simultaneous observations of the same precipitation event by multiple radars operating at the attenuating frequency such as X-band and scanning in a low elevation ...

Operational and research radar networks in Korea
2017 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2017Currently, to observe entire Korean peninsula, two operational S-band radar networks have been operated by the KMA and the MOLIT. In this paper these two radar networks will be described in aspects of their goals and collaboration. In addition, two research X-band radar networks which will be deployed in Seoul and western sea side of Korean peninsula ...

HRRP recognition in radar sensor network
Ad Hoc Networks, 2017Abstract In this paper, several high-resolution range profile (HRRP) recognition approaches in radar sensor network (RSN) are investigated. First, we study HRRP target recognition in a radar. A decision rule based on the minimum resistor-average (MRA) distance criterion is established for HRRP sequence recognition.

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 ...

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.

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

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.

Opportunistic Radar in IEEE 802.11ad Networks
IEEE Transactions on Signal Processing, 2018In this paper, we study the feasibility of an opportunistic radar, which exploits the probing signals transmitted during the sector level sweep of the IEEE 802.11ad beamforming training protocol. Several solutions are presented to detect the presence of prospective obstacles and estimate their position, radial velocity, and backscattered signal ...
