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 ...

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

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.

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.

Decentralized processing in radar networks [PDF]
IET International Conference on Radar Systems 2007, 2007 In this paper we apply a sub-optimum algorithm to a radar network with a double threshold for detection and we report the results for two types of decision rules. The algorithm presented nearly maintains detection performance in the presence of jamming and is achieved without any of the countermeasures more commonly adopted.

NeXtRAD and RHINO radar: Harnessing the herd for networked radar
2014 International Radar Conference, 2014This paper demonstrates the use of open source hardware and software to implement the digital back end of a network of radars. i.e. RHINO platform - a highly capable reconfigurable platform serving both digitisation / synthesis and packetisation functions for a dual X and L band radar. The system is capable of arbitrary waveform generation for transmit,

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 ...
