How far can a radar gun reach?

I was wondering how far a radar gun could reach. Let's assume its the most range. What is the max range for radar as of today?

Thanks

Glad to help. The other thread came up yesterday so I knew just where to get it. I've seen lots of other guys on here do the same. Its a great forum.

When it comes to radar, its all about "Line of Sight" and the beam width of the transmitting device. Most radar devices...I think, run anywhere from 5 to 17 degrees beam width. Now given that the horizon of the planet itself, yes...the whole Earth, is 11 miles out, radar cannot see past that distance even with a small beam width. Of course, a LEO can't see you 11 miles away either normally unless he's sitting on a hill. What comes to my mind right away is I-15 out of Las Vegas at the Nevada/California border. A CHP up the hill which happens to be 11 miles away, can indeed see someone coming south but painting a radar target on him will be next to impossible due to a few hundred to a few thousand other cars all going the same direction.
