Using hardened armor plate (as used for steel "gong" targets) can get that down 
under a half inch, resulting in a lot less mass to drag downrange and back. It 
won't hurt to locate the sensor behind a berm, either. The sky screen and/or 
its supports will still get shot eventually, but that will be a lot cheaper to 
replace than the sensor.
