Probably wont get an answer but how does a radar gun sense the ball release point of a pitcher to determine the speed of a pitch

A radar gun measures the speed of a pitched baseball by detecting the Doppler shift in the frequency of a microwave signal that is reflected off the ball. The radar gun sends out a continuous wave of microwaves at a specific frequency. When the ball passes through the microwave beam, some of the microwaves are reflected back to the radar gun. The reflected microwaves have a different frequency than the original microwaves, due to the Doppler shift. The Doppler shift is proportional to the speed of the ball. The radar gun measures the Doppler shift and uses it to calculate the speed of the ball.

The radar gun must be positioned so that the microwave beam is perpendicular to the path of the ball. The radar gun also needs to be calibrated to the correct frequency for the ball being pitched.

Here are 5 related questions with brief answers:

What is the Doppler shift? The Doppler shift is the change in frequency of a wave that occurs when the source of the wave is moving.
How does a radar gun use the Doppler shift to measure the speed of a pitch? The radar gun sends out a continuous wave of microwaves and measures the Doppler shift in the frequency of the reflected microwaves to calculate the speed of the ball.
How accurate are radar guns? Radar guns are very accurate, but they can be affected by factors such as the weather and the distance from the ball.
What are the limitations of radar guns? Radar guns can only measure the speed of a ball that is moving in a straight line.
What are some of the uses of radar guns? Radar guns are used to measure the speed of pitched baseballs, as well as the speed of other objects such as cars and airplanes.
