MEASURING A TENNIS SERVE
CORRECT SET-UP

Carefully aim the radar beam directly toward the ball as it makes contact with the racket. Adjust the radar height and tilt accordingly creating a radar beam, the ball needs to travel down this beam.
The ball needs to be hit just above the net, right over the radar.
Position the radar behind the net to prevent it from getting hit. The court distance provides the required 15-20 feet the radar needs to be away from the athlete, allowing the spot size of the radar beam to spread out. Hit the ball directly in line with the radar beam. Only count the speeds where the ball goes directly toward the radar.

To measure the maximum speed of a tennis serve, it is very important to aim the radar properly.
The radar needs to tilt up to create a beam for the ball to travel down, picking up the top speed as the ball makes contact with the racket.
In this example, the radar is not aimed in line with the path of the ball, the ball doesn’t enter the radar beam at all.
