I'll leave the final call to some of the brighter list members, but from
all 
the literature I've read on the Longbow system, the millimetric-wave
radar is 
a passive system.  I know it seems contradictory, but it is supposed to 
detect the disturbances in radio frequencies caused by large masses like

tanks and have the definition to indetify them by type.  My immediate 
reference for this is Army Technology's Apache entry at 
<http://www.army-technology.com/projects/apache/index.html> under the
heading 
of Missiles ("The Longbow fire control radar incorporates an integrated
radar 
frequency interferometer for passive location and identification of
radar 
emitting threats. An advantage of millimetre wave is that it performs
under 
poor visibility conditions and is less sensitive to ground clutter. The
short 
wavelength allows a very narrow beamwidth which is resistant to 
countermeasures.").  

And now, back to your regularly scheduled selection of GZG 
product/settings/rules debates.
