* Radar altimeters measure an aircraft's true height above ground.

Data from Radar altimeters are used for the accurate determination of the geoid, monitoring of tides, ocean currents and other large-scale ocean phenomena such as El Niño.

Two Soviet spacecraft ( Venera 15 and Venera 16 ) imaged the planet in 1983 and 1984 using SAR and Radar altimeters.

The common types of remote sensing are Radar, Lidar, and satellites ( or photogrammetry ).

Radar and Lidar are not passive because both use EM radiation to illuminate a specific portion of the atmosphere.

Radar signals are reflected especially well by materials of considerable electrical conductivity — especially by most metals, by seawater, by wet land, and by wetlands.

Radar receivers are usually, but not always, in the same location as the transmitter.

Radar video returns from aircraft can be subjected to a plot extraction process whereby spurious and interfering signals are discarded.

Radar corner reflectors made of metal are used to reflect radio waves from radar sets.

Radar corner reflectors are designed to reflect the microwave radio waves emitted by radar sets back toward the radar antenna.

Two prominent locations in the park are Point Stephens Light, a lighthouse built in 1862 and the World War II gun emplacements on Tomaree Head which were built in 1941, the location of the No. 20 Radar Station RAAF.

The Radar Rangers are an amateur radio enthusiast group that helps Buckaroo track major threats.

Multipath in Pulse Position Modulation systems can be easily mitigated by using the same techniques that are used in Radar systems that rely totally on synchronization and time of arrival of the received pulse to obtain their range position in the presence of echoes.

Imaging from NASA's Shuttle Radar Topography Mission STS-99 reveals part of the 180 kilometre ( 112 mi ) diameter ring of the crater ; clustered around the crater's trough are numerous sinkhole s, suggesting a prehistoric oceanic basin in the depression left by the impact.

Once departing aircraft are away from the airport, responsibility is taken over by Oslo Air Traffic Control Center, which supervises the airspace with Haukåsen Radar.

* The Radar Room, the security centre from which craft approaching or leaving Cloudbase are tracked

Radar and optical detectors such as lidar are the main tools used for tracking space debris.

Air Traffic Services are provided by dedicated Air Traffic Controllers in the tower and the Terminal Radar Approach Control.

The main elements of an aircraft's avionics are its communication and navigation systems, sensors ( Radar and IR ), computers and data bus, and user interface.

Sightings more than 500 feet ( 160 m ) from the witness are classified as " Daylight Discs ," " Nocturnal Lights ," or " Radar / Visual Reports.

Studies for putting a Griffo Radar in the nose are well under way.

There are six officially released maps that are partially based on real locations or events ( North African Campaign: Gold Rush, Siwa Oasis, and Atlantic Seawall Battery ; Europe Campaign: Rail Gun, Würzburg Radar, and Fuel Dump ), as well as hundreds of custom maps made by the Internet community.

There are four research divisions: Radar, Information Technology, Optical Sciences, and Tactical Electronic Warfare.

Radar guns that operate using the X band ( 8 to 12 GHz ) frequency range are becoming less common because they produce a strong and easily detectable beam.

Radar detectors are illegal in some areas.

Two separate competing systems are currently operating within the US, Common ARTS ( Automated Radar Terminal System ( Lockheed Martin )) and STARS ( Raytheon ), with Common ARTS operating at the busiest facilities ( NY, Dallas, Atlanta, Southern California, Chicago, Washington DC area, Denver, St Louis, Minneapolis and San Francisco area ) within the US.

Radar altimeter technology is also used in terrain-following radar allowing fighter aircraft to fly at very low altitude.

" (" Darkstar " is also a call sign of AWACS aircraft from a different squadron at Tinker AFB ) A month later, radio enthusiasts in California monitoring Edwards AFB Radar ( callsign " Joshua Control ") heard early morning radio transmissions between Joshua and a high flying aircraft using the callsign " Gaspipe ".

One way of accomplishing this is to chirp the RADAR signal ( also known as Chirp Radar ).

His M * A * S * H character Radar O ' Reilly was spun off into an unsold TV show called W * A * L * T * E * R. Burghoff also appeared in an episode of The New Adventures of Wonder Woman " The Man Who Wouldn't Tell " in 1978, where he was reunited with his former band member Diana Prince a. k. a. Wonder Woman ( played by Lynda Carter ).

The members of the department also receive the required DCJS courses for peace officers to perform traffic enforcement duties including Radar / LIDAR, Standard Field Sobriety, Basic Crash Management, etc.

It also extends 5 – 6 miles to the north, where it is called Sage Hill and then rises a bit higher at Radar Hill, named for an old World War II Radar base installed at the peak.

He lives in a large nest behind the 123 Sesame Street brownstone ( which had to be completely rebuilt during Season 32 after it was destroyed by a hurricane ) and he has a teddy bear named Radar, after Walter " Radar " O ' Reilly of M * A * S * H, who had a teddy bear and was also lovably naive and innocent.

She was also immortalized in Golden Earring's 1973 hit " Radar Love ": " Radio's playing some forgotten song / Brenda Lee's ' Coming on Strong '.

The Proyecto Arqueologico Pumapunku-Akapana ( PAPA, or Pumapunku-Akapana Archaeological Project ) run by the University of Pennsylvania, has been excavating in the area surrounding the pyramid for the past few years, and also conducting Ground Penetrating Radar surveys of the area.

The Nike Zeus system also included the Zeus Acquisition Radar ( ZAR ), a significant improvement over the Nike Hercules HIPAR system.

Radar can also detect a submarine snorkel or periscope, and the wake it creates.

To measure the range to the target under jamming conditions the IFC was also equipped with a Target Ranging Radar ( TRR ).

Intel 960 processor is also used in Automatic Radar Plotting Aid ( ARPA ) interfacing boards of radars from Kelvin Hughes.

On Saturday, 16 April 1994, 12: 30 p. m. CDT, the Space Radar Lab-1 instruments also were continuing to operate well, and all observations were being made on schedule.

Upravlyaemy Sputnik Aktivnyj (), or US-A, also known in the west as Radar Ocean Reconnaissance Satellite or RORSAT, was a series of Soviet reconnaissance satellites.

The follow-up single " Turn on Your Radar " also charted, becoming their fifth and final American hit.

One aircraft application at the Canada Centre for Remote Sensing produced digital elevation maps with a resolution of 5 m and altitude errors also on the order of 5 m. Interferometry was used to map many regions of the Earth's surface with unprecedented accuracy using data from the Shuttle Radar Topography Mission.

The Space Shuttle has also carried synthetic-aperture radar equipment during the SIR-A and SIR-B missions during the 1980s, as well as the Shuttle Radar Laboratory ( SRL ) missions in 1994 and the Shuttle Radar Topography Mission in 2000.

Synthetic-aperture radar was first used by NASA on JPL's Seasat oceanographic satellite in 1978 ( this mission also carried an altimeter and a scatterometer ); it was later developed more extensively on the Spaceborne Imaging Radar ( SIR ) missions on the space shuttle in 1981, 1984 and 1994.

It is also a reason why NATO in its NATO Anti-Air Warfare System study ( NAAWS ) defined the preferred AAW system as consisting of a complementary Volume Search Radar and MFR.

Varaždin is also the host of the " Radar festival ", which hosts concerts at the end of summer.
