Radar Gun for measuring speed

Can this unit measure the speed of oa moving vehicle from another moving vehicle or do you have such a unit?

As far as I know none of the radar guns are designed to be able to measure the speed of a vehicle from another moving vehicle. The Bushnell Radar Guns models are definitely not sophisticated enough to be able to handle the task, but at the same time neither are the Decatur Radar Guns, which are the best units for traffic control around. Decatur Electronics is what is used by law enforcement agencies.

Sorry that I was not able to answer your question.

As far as I know about that, radar gun or speed gun is a small Doppler radar unit used to detect the speed of objects, especially trucks and automobiles for the purpose of regulating traffic, as well as pitched baseballs, runners or other moving objects in sports. A radar gun does not return information regarding the object's position. It relies on the Doppler Effect applied to a radar beam to measure the speed of objects at which it is pointed. Radar guns may be hand-held or vehicle-mounted.

I don't know if this information will help you answer your questions but I still hope I helped you
