International Journal of Imaging Systems and Technology, 1992
AbstractRadar systems combining coherent signals with frequency and angular diversity offer the possibility of synthesizing images of complex objects with spatial resolution of a few wavelengths. The availability of high‐quality microwave sources and components, high‐speed digital computers, and efficient signal‐processing algorithms allows radar ...

Radars de Surface - Radars Civils et Radars Côtiers
Technologies radars et applications, 2014Cet article presente les radars qui operent au sol ou sur un navire. Dictinction est faite tout d'abord, parmi les radars de surface, entre les radars primaires (de veille, de poursuite, multifonction) et les radars secondaires (de surveillance, d’identification). Sont ensuite decrits les radars civils et les radars cotiers. Pour chacun de ces domaines,

IEEE International Radar Conference, 2005., 2005
In the search for a better rotating radar, a self-supporting array that rolls like a wheel can improve mechanical reliability and return higher-definition target resolution. The Rolling Radar concept evolved from the need to design and build a large rotating 3D radar as an alternative to multifaceted fixed radar installations, or large, expensive ...

Radar resource management in multifunction radar
2010 International Conference On Computer Design and Applications, 2010In this paper, a multifunction radar system architecture has been introduceed. Multifunction radar is a phased array radar system. A phased array radar system can adapt its parameters on a near-instantaneous basis according to the way in which it perceives its operating environments.

Team Radar: A Radar Metaphor for Workspace Awareness
2013In distributed software teams, awareness information is often lost due to communication restrictions. Researchers have attempted to retain team awareness by sharing change information across workspaces. The major challenge is how to convey information effectively while avoiding information overload.

Introduction to radar and radar communications
2017Radio detection and ranging (RADAR) is a method of using electromagnetic waves to determine the position of a target. Radar transmits a signal and receives and detects a portion of the signal that is reflected back to the radar. Radar uses this return signal or echo to measure the time it is transmitted to the time it is received to determine the range

2016 9th International Kharkiv Symposium on Physics and Engineering of Microwaves, Millimeter and Submillimeter Waves (MSMW), 2016
Preliminary results of the comparative analysis of Quantum Radar (QR) based upon quantum entanglement phenomenon and Noise Radar (NR) based upon classical coherence notion and correlation processing of random signals are presented in the paper. It has been shown that the basic idea of entangled multi-photon QR for simultaneous implementing of high ...

Radar Transponders and Radar Target Enhancers
Journal of Navigation, 1995Radar transponders and radar target enhancers have been in use in a variety of applications for many years. Perhaps the most widely-known applications of radar transponders are in Identification Friend or Foe (IFF) and its civilian counterpart, secondary surveillance radar for air traffic control, and as racons in marine navigation and, most recently ...
