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,

Precipitation radars scan their vicinity to determine the location, intensity, and structure of showers and storms. Several different radar variables are used to determine different aspects of the precipitation. Radar reflectivity measures the number and size of particles. In radars that transmit and receive horizontally as well as vertically polarized

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.

Radar receiver burnout by other radars
IEE Proceedings A Physical Science, Measurement and Instrumentation, Management and Education, Reviews, 1981A radiation hazard perhaps not generally given sufficient attention is that of one high-power radar burning out the receiver of a nearby system as a result of power coupling via their aerials. A review of various receiver peak-power withstands reveals that pulse power of 0dBW is a suitable working figure for such studies, although individual devices ...

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 ...

Quantum Radar and Noise Radar Concepts
2021 IEEE Radar Conference (RadarConf21), 2021Comparative analysis of Noise Radar (NR) and Quantum Radar (QR) concepts are presented in the paper. Recently proposed methods for generation of quantum correlated signals directly in microwave frequency range give more chances for design of QR for long-range applications.

Geo-radar in tunneling - The radar tunnel
Fourth International Conference on Ground Penetrating Radar, 1992Between 75 and 100 kilometres of tunnel are excavated in Norway each year. In many of these tunnelling projects, the contractor is looking for methods to acquire geological information during the excavation process, enabling him to carry out the project safely and in a cost effective manner.
