long-range surveillance radar

long-range surveillance radar

The primary radar used for airways surveillance, long-range air defense, etc., up to ranges of 200 to 300 NM. These primary radar provide range and bearing (i.e., positional information), which in some areas may be supplemented by a height-finding surveillance radar.

Originally purchased in 1988, the Long-Range Surveillance Radar is a ground-based air surveillance radar system capable of detecting objects in distant and high altitudes.
The system equipment, apart from the APAR itself includes the SMART-L long-range surveillance radar and Mk4l VLS for SM-2 area-defense SAMs and Evolved Sea-Sparrow (ESSM) point-defense missiles.
Mobility allows a radar to be moved to where it is needed in the light of current tactical circumstances, either to cover a new sector, or to replace a system which has been destroyed in combat, but the sheer size of a long-range surveillance radar means that set-up and tear-down time can be measured in hours.
Tactical surveillance radars and the surveillance sets used by surface-to-air missile systems have more modest range requirements, so can use higher frequencies and thus much smaller aerials, but have practical limits in transmitter and receiver technology, and the need to avoid absorption of the radar energy by atmospheric water vapour make it unlikely that the antenna of future long-range surveillance radars will be significantly smaller than today's equivalent models.
In addition to SAMPSON, the UK PAAMS variant also comprises the Aster 15 and 30 active homing surface-to-air missiles, a 48-cell SYLVER vertical launcher system, a command and control package, and the D-band (1 to 2 GHz) S1850M multibeam long-range surveillance radar. The Aster missiles used in the PAAMS system are capable of speeds and maneuvers in excess of Mach 4 and 50G, respectively.

"Together with military air traffic, this situation requires a high-performance guidance system ensuring safety, comprehensive data exchange and efficient allocation of airspace." Under the project aRamosa, Airbus Defence and Space Electronics has equipped six long-range surveillance radars with so-called MSSR (MSSR = Monopulse Secondary Surveillance Radar) 2000 I secondary radar systems.
For birds, this distance may vary from a few hundred meters for the smallest marine radars to over 150 kilometers (93 miles) in the case of long-range surveillance radars.
