Some Basic Notes About Types Of Speed Gun Of A Radar Detector For Car
Two types of laser guns
The speed gun by laser use a direct method based on the response time of light instead of changing Doppler principle, according to this radar detector reviews. You may have experienced a response in the form of sound waves echo. For example, as you say a deep down well or shout at the canyon, the sound that will take some time to touch the bottom of the well and then turn back to your ears. Sound waves move at the speed of 300 meters per second (1,000 feet) so if you speak a deep down well or a large canyon, the echo becomes very clear.
A laser gun shooting speed will calculate the amount of time to light touch objects then come back. Light from a laser gun sound move a lot faster, about 300,000,000m per second (984 million feet) or equivalent 30cm/ nano-seconds. Laser guns emit a red laser beam, which is very short and then wait for it to respond to the car. Guns will calculate the number of nano-seconds required to laser it off and on, and then divided by 2 to calculate the distance to the vehicle.
If that gun out of action performes 1000 times / second, it can calculate the distance between each measurement and then calculate the speed of the vehicle. By implementing a few hundred times measured in 1/3 seconds, the accuracy will be very high.
Example of speed radar gun
What is the essence of speed radar gun technology? We should review the information on the type of speed gun and the principle of operation of radar guns (stands for Radio Detection And Ranging) and laser:
Police began using radar (speed gun) called X-Band with frequency of 10.525GHz until the mid 70’s of last century. This type of X-Band is easily detected, so they switched to use a K-Band in 1976 with the scope of operation in frequencies from 24.5–24.25GHz (precision is about 24.150GHz). Ka-Band then is between 33.4 and 36.0GHz which the operation is put into use in 1989. The weapon laser then is also put to use. Whenever police introduced a new radar, the manufacturer is also unveiled shortly RD detect those kinds of new weapons.
Number of firearms in vogue?
To see clearly the number of firearms in vogue, you had better know Valentine One V1 review that you can search for easily. At a previous statistipolice, in the US, there are about 5% of the 100K speed radar gun is kind of X-Band, 60% use a K-Band and 35% work with Ka-Band. These numbers change over time and more and the speed gun type X-Band format has been replaced by newer types such as K and Ka-Band. Laser guns have also begun to be applied more common.
New Technology
The newer guns have extra 2 special features, which are Fastest Speed and Same Lane. Same Lane is a technology that allows guns to locate the object as it moves along, Fastest Speed also allows to filter the fastest vehicle of the vehicle, which is moving.
