This inability to differentiate among targets in the radar's field of view is the primary reason for the operator being required to consistently and accurately visually estimate target speeds to within +/-2mph, so that, for example if there are seven targets in the radar's field of view and the operator is able to visually estimate the speed of six of those targets as approximately 40mph and visually estimate the speed of one of those targets as approximately 55mph and the radar unit is displaying a reading of 56mph it becomes clear which target's speed the unit is measuring. It’s really easy and fun to use Tennis Serve Speed Radar Gun an indispensable tool for when you’re having fun or practicing and improving your skills! If a hand held radar can get within around 1.5MPH of the true speed of a ball, I’d say it’s pretty accurate.

Just as two different musical notes played together create a beat note at the difference in frequency between them, so when these two radio signals are mixed they create a "beat" signal (called a heterodyne). An electrical circuit then measures this frequency using a digital counter to count the number of cycles in a fixed time period, and displays the number on a digital display as the object's speed.

The vision of the speed gun is wide and includes more than just the ball. You may now wonder how it knows to focus on the tennis ball. Use a radar gun with motor sports. Look for a radar gun that continuously measures speed, which will tell you when the vehicle slows down unexpectedly. Or you might want a radar gun that only displays the top speed, such as for a straightaway or for drag racing. The gun must have a speed measurement range that can match your vehicle. Some radar guns top out at 150 miles per hour, while others measure up to 200 or 250 miles per hour.

Sports Ball Radar Speed Gun - SRA3000 Tracer

A radar speed gun is a Doppler radar unit that may be handheld, vehicle-mounted, or static. It measures the speed of the objects at which it is pointed by detecting a change in frequency of the returned radar signal caused by the Doppler effect, whereby the frequency of the returned signal is increased in proportion to the object's speed of approach if the object is approaching, and lowered if the object is receding. [3] Such devices are frequently used for speed limit enforcement, although more modern LIDAR speed gun instruments, which use pulsed laser light instead of radar, began to replace radar guns during the first decade of the twenty-first century, because of limitations associated with small radar systems. The speed radars will be aimed toward the players and the ball, but the angle is not very important.
