Helpful Facts in Understanding Radar Guns

Batter about to hit a ball

Do you know what device measures the velocity of a moving object? It is a radar gun, intended for use by police officers to record the speed of traveling vehicles. Eventually, it found uses for other purposes, like helping sports scouts establish the speed of thrown pitches through to baseball radars.

The radar gun has already evolved since its introduction. You can buy these devices from reputable online vendors such as radargunsales.com. Here are some helpful facts about radar guns that you should know.

The way it works

Your radar gun works with the Doppler Effect, which has something to with the producer of the waves (the source), and the receiver of the waves (the observer). In this effect, both the observer and source are moving to each other relatively. That is when scientific relativity is formed.

You measure the speed of the object by identifying the changes in the frequency once pointed at your target.

The low-speed device

Do you know that there is also a low-speed radar gun? You heard it right! Scientists created a low-speed radar gun to capture speed as low as one MPH. They use this normally for skaters, runners, warehouse vehicles, forklifts, even for education and scientific studies, among others.

The cosine effect angle

The path of your target and your radar is called the cosine effect angle. If your target is moving towards or away from your radar, there is no error since the cosine effect angle is zero degrees. You have to remember that if the angle is greater, the bigger the error.

The effect of the environment

Your environment absolutely affects the performance of your radar gun. Like the rain, wind and your mobile phone could also cause interference.

Now that you have learned more about radar guns, you can fully maximize its use.
