Radar mile. Radar mile or radar nautical mile is an auxiliary constant for converting a (delay) time to the corresponding scale distance on the radar display. [1] Radar timing is usually expressed in microseconds. To relate radar timing to distances traveled by radar energy, you should know that radiated energy from radar set travels at ...
In radar -related subjects and in JTIDS, a data mile is a unit of distance equal to 6000 feet (1.8288 kilometres or 0.987 nautical miles ). An international mile is exactly 0.88 of a data mile. The speed of light is 983571056 ft/s, or about one foot per nanosecond. If it were exactly one foot per nanosecond, and a target was one data mile away ...
Mile Road System (Michigan) Several counties in the state of Michigan use a Mile Road System to name different roads and streets. The most commonly known system is that of Detroit, including 8 Mile Road, the dividing line between Detroit and its northern suburbs as well as Wayne County and Oakland, Macomb and Washtenaw counties.
Health threats from cosmic rays are the dangers posed by cosmic rays to astronauts on interplanetary missions or any missions that venture through the Van-Allen Belts or outside the Earth's magnetosphere. [1] [2] They are one of the greatest barriers standing in the way of plans for interplanetary travel by crewed spacecraft, [3] [4] [5] but ...
Linda Melson Harrison (born July 26, 1945) is an American television and film actress. She played Nova in the science fiction film classic Planet of the Apes (1968) and the first sequel, Beneath the Planet of the Apes; she also had a cameo in Tim Burton's 2001 remake of the original.
Radiant intensity is used to characterize the emission of radiation by an antenna:, = (), where E e is the irradiance of the antenna;; r is the distance from the antenna.; Unlike power density, radiant intensity does not depend on distance: because radiant intensity is defined as the power through a solid angle, the decreasing power density over distance due to the inverse-square law is offset ...
A nautical mile is a unit of length used in air, marine, and space navigation, and for the definition of territorial waters. [2] [3] [4] Historically, it was defined as the meridian arc length corresponding to one minute ( 1 60 of a degree) of latitude at the equator, so that Earth's polar circumference is very near to 21,600 nautical ...
The mile, sometimes the international mile or statute mile to distinguish it from other miles, is a British imperial unit and United States customary unit of length; both are based on the older English unit of length equal to 5,280 English feet, or 1,760 yards. The statute mile was standardised between the Commonwealth of Nations and the United ...
