Radar FAQs:

Q: Is a radar an object-detection system that uses radio waves to determine the range?

A: Yes, and angle, or velocity of objects.

Q: Is a radar based on frequency modulation?

A: Yes.

Q: Was a radar the Mikoyan MiG-31?

A: Yes.

Q: Is a radar highly diverse?

A: Yes, and including air and terrestrial traffic control, radar astronomy, air-defence systems, antimissile systems, marine radars to locate landmarks and other ships, aircraft anticollision systems, ocean surveillance systems, outer space surveillance and rendezvous systems, meteorological precipitation monitoring, altimetry and flight control systems, guided missile target locating systems, ground-penetrating radar for geological observations, and range-controlled radar for public health surveillance.

Q: Were radars originally used for missile defence?

A: Yes, They are the heart of the ship-borne Aegis Combat System and the Patriot Missile System.

Q: Was a radar coined in 1940 by the United States Navy as an acronym for RAdio Detection And Ranging or RAdio Direction And Ranging?

A: Yes.

Q: Are radars valued for use in aircraft since they can track multiple targets?

Q: Is a radar aimed upwards at clear sky?

A: Yes, where the scene is so "cold" that it generates very little thermal noise.

Q: Was a radar considered to be the world's most powerful fighter radar?

A: Yes, until the AN/APG-77 Active electronically scanned array was introduced on the Lockheed Martin F-22 Raptor.

Q: Are radars used to measure the bearing and distance of ships to prevent collision with other ships?

A: Yes, and to navigate, and to fix their position at sea when within range of shore or other fixed references such as islands, buoys, and lightships.

Q: Is a radar connected?

A: Yes, and a radar tracker is used to associate the sequence of plots belonging to individual targets and estimate the targets' headings and speeds.

Q: Is a radar ideal for determining the radial component of a target's velocity?

A: Yes.

Q: Was a radar developed secretly for military use by several nations in the period before and during World War II?

A: Yes.

Q: Is a radar typically used by traffic enforcement to measure vehicle speed quickly and accurately where range is not important?

A: Yes.
