A radar is a device that uses electromagnetic waves to detect the presence, location, speed, and other characteristics of distant objects, such as planes, ships, cars, and other vehicles. The term “radar” is an acronym for “Radio Detection and Ranging”
Radar works by emitting a pulse of high-frequency electromagnetic waves that travel through the air at the speed of light. These waves bounce off objects they encounter on their way back to the radar, where they are collected and processed to determine the distance, direction and speed of the objects. The collected information is displayed on a screen so that radar operators can analyse it and make decisions accordingly.
Radars are used in a wide variety of applications, such as air and maritime navigation, air traffic control, highway and highway traffic management, weather surveillance, scientific research, and military and homeland security, among others. applications.
How speed cameras work in Spain
In Spain, the margin of the fixed and mobile speed cameras of the DGT follows the rule of 5 and 7 to fine. In other words, in measurements below 100 km/h, +/-5 km/h for fixed radars and +/-7 km/h for mobiles installed in a vehicle; and in measurements above 100 km/h, +/-5 or +/-7%.
Now, with the entry into force of the Ministerial Order regulating the metrological control of the State, the new radars are approved in another way: Fixed radars with static installation, the margin in measurements below 100 km/h is 3 km/h and in those with higher measurements it is 3%
Mobile radars have a maximum error of 5 km/h in the case of measurements below 100 km/h and 5% in measurements above that speed.
The section radars, for their part, work the same as the new radars. +/-3 km/h or +/-5 km/h in the case of measurements below 100 km/h, and +/-3% or +/-5 in the case of measurements above 100 km/h .
