The radar mile is a unit of time (in the same way that the light year is a unit of distance), equal to the time required for a radar pulse to travel a distance of two miles (one mile each way). Thus, the radar statute mile is 10.8 μs and the radar nautical mile is 12.4 μs.
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, the speed is used to calculate it.
The time difference between interrogation and reply minus the 50 microsecond ground transponder delay, and the pulse spacing of the reply pulses (12 microseconds in X mode and 30 microseconds in Y mode), is measured by the interrogator's timing circuitry and converted to a distance measurement (slant range), in nautical miles, then displayed on ...
In the IANA time zone database, Tunisia is given one zone in the file zone.tab – Africa/Tunis."TN" refers to the country's ISO 3166-1 alpha-2 country code.Data for Tunisia directly from zone.tab of the IANA time zone database; columns marked with * are the columns from zone.tab itself: [5]
Time zones of the world. A time zone is an area which observes a uniform standard time for legal, commercial and social purposes. Time zones tend to follow the boundaries between countries and their subdivisions instead of strictly following longitude, because it is convenient for areas in frequent communication to keep the same time.
Holiday Stress and Anxiety: 6 Ways to Cope. The holiday season is often called the most wonderful time of the year — but for many, it can actually be the most stressful time of year.
With one exception (magnetic declination), they all depend on a common principle, which is to determine the time for an event or measurement and to compare it with the time at a different location. Longitude, being up to 180° east or west of a prime meridian, is mathematically related to time differences up to 12 hours by a factor of 15. Thus ...
