Civil aviation radars tend to be concentrated in the band 2 700–2 900 MHz, although the use of the band 2 900–3 400 MHz is increasing
The major users in the band 2 900–3 400 MHz are radionavigation radars for maritime purposes and radiolocation radars for national defence purposes
Some countries are reviewing the long-term requirement for PSR
What is air traffic control and navigation radar?
Air traffic control and navigation radar is used by airports to ensure the safety of planes
This type detects the proximity of an aircraft and identifies the identity and altitude of the plane
Radio beacons and Distance Measuring Equipment (DME) also fall into this category
What is aircraft weather radar?
In aircraft weather radar, these radio waves are meant to bounce off precipitation types, such as rain, hail, and snow
On the other hand, they are meant to bounce off of aircraft in Air Traffic Control
Signals that are returned to the receiver are of varying intensities
Aviation radar
Type of radar equipment
A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal. This variation gives direct and highly accurate measurements of the extiw>radial component of a target's velocity relative to the radar. The term applies to radar systems in many domains like aviation, police radar detectors, navigation, meteorology, etc.
Duga was an over-the-horizon radar (OTH) system
Soviet over-the-horizon early-warning radar system
Duga was an over-the-horizon radar (OTH) system used in the Soviet Union as part of its early-warning radar network for missile defense. It operated from July 1976 to December 1989. Two operational duga radars were deployed, with one near Chernobyl and Chernihiv in the Ukrainian SSR, and the other in eastern Siberia.
A fire-control radar (FCR) is a radar that
Narrowly focused radar beam whose reflected signal is used to obtain a missile lock-on
A fire-control radar (FCR) is a radar that is designed specifically to provide information to a fire-control system in order to direct weapons such that they hit a target. They are sometimes known as narrow beam radars, targeting radars, or in the UK, gun-laying radars. If the radar is used to guide a missile, it is often known as a target illuminator or illuminator radar.
Precision approach radar or PAR is a type
Type of radar guidance system
Precision approach radar orPAR is a type of radar guidance system designed to provide lateral and vertical guidance to an aircraft pilot for landing, until the landing threshold is reached. Controllers monitoring the PAR displays observe each aircraft's position and issue instructions to the pilot that keep the aircraft on course and glidepath during final approach. After the aircraft reaches the decision height (DH) or decision altitude (DA), further guidance is advisory only. The overall concept is known as ground-controlled approach (GCA), and this name was also used to refer to the radar systems in the early days of its development.
Radar navigation is the utilization of marine and aviation
Radar navigation is the utilization of marine and aviation radar systems for vessel and aircraft navigation. When a craft is within radar range of land or special radar aids to navigation, the navigator can take distances and angular bearings to charted objects and use these to establish arcs of position and lines of position on a chart. A fix consisting of only radar information is called a radar fix.
Type of missile guidance system
Semi-active radar homing (SARH) is a common type of missile guidance system, perhaps the most common type for longer-range air-to-air and surface-to-air missile systems. The name refers to the fact that the missile itself is only a passive detector of a radar signal—provided by an external (offboard) source—as it reflects off the target. Semi-active missile systems use bistatic continuous-wave radar.
In United States aviation, a terminal radar service area (TRSA) is a delimited airspace where radar and air traffic control services are made available to pilots flying under instrument flight rules or (optionally) visual flight rules, to maintain aircraft separation.
