In Tennessee a few years ago along the Natchez highway the police had
installed multiple devices under bridges or behind signs to spew Ka-band
radar signals onto the roadway, doing pretty much what you're asking about.
It was effective for about, oh, the first 3 times you drove the route, then
it was mentally noted and very predictable.  I guess this application never
really caught on, since I haven't seen them around for quite a while.
