Raytheon's IMS [Integrated Maritime Surveillance] uses land-based long-range surface wave radar, which transmits high frequency(HF) radio waves that follow the earth's curvature. The SWR-503 Surface Wave Radar detects and tracks aircraft, surface vessels and icebergs out to 500 km from the shore in a sector of up to 120 degrees. The radar also provides current and surface wind data. At an Operations Control Centre, the IMS system correlates detections from surface wave radar sites with identification information from ADS systems and other sensors. All of this data is fused to create a database and display system providing a complete picture of surface and air activity in the EEZ. Vessel tracks can be run backward and forward in time, enhancing military patrols and coast guard search-and-rescue efforts as well as oil spill control, drug interdiction, and iceberg alerts. Applications for HF Surface Wave Radar are being developed in fields such as Theatre Ballistic Missile and Meteor Shower Detection.  5, record 1, English, - high%2Dfrequency%20surface%20wave%20radar

Primary radar is(...) the original form of radio-detection, in which a beam of microwave energy illuminates a passive or "non-cooperating" target and the reflected pulse or echo is processed to display its bearing and distance from the transmitter(three-dimensional or height-finder radars will also display its altitude, although these are, so far, restricted to military surveillance applications, essentially for reasons of cost, plus the fact that there are alternative means of determining the altitude of aircraft, other than hostile intruders).  1, record 2, English, - passive%20target

Le radar primaire, c'est (...) la forme originale de la détection électromagnétique: un faisceau de micro-ondes est envoyé sur une cible passive et le signal réfléchi par celle-ci est traité pour en déterminer et faire apparaître sur un écran le relèvement et distance par rapport à l'émetteur (les radars tridimensionnels indiquent en outre l'altitude de la cible mais, essentiellement pour des raisons de coût et parce qu'il est possible de déterminer l'altitude des aéronefs amis par d'autres moyens, leurs applications sont actuellement limitées à la surveillance militaire).  1, record 2, French, - cible%20passive
