If you go farther back in C/D (before the prevalence of laser), there
was an issue that discussed how the vertical metallic surfaces
reflected a lot of the radar signal. (That's when they mentioned the
Vette's inherent advantage due to the radiator angle.) I could find
out which issue, but it would take hours of rooting through boxes in
my basement (12 years' worth) -- articles like that one aren't indexed
like the road tests, so I would have to check all the tables of
contents. The information in that article may be somewhat dated
anyway, since a lot of time has passed.
You're right, the laser issue is more recent (and pretty interesting
-- I want one of those IR filters!). However, I think I've already
relegated that one to the basement, too. If I happen to come across
it, I'll post the issue date. Don't hold your breath, though; I'm
about to leave on vacation, so I won't be hanging out in the basement
