Police have been using radar for that purpose for decades. Laser based technology might also work for you.
Hello engineers and experts
What technologies/measuring instruments makes it possible for a stationary object to track speed and distance (in height, length and width) to a moving object?
The distance between the two objects will be no more than 300 feet, and the measurement of the distance between the two objects must not deviate by more than 4 inches.
I really hope you can help!
Thank you in advance,
Emil
