In the light of Alan B. Pearce's posting with PIN modulators the
flurescent light 'jammer' (with spiral around it) makes a lot of sense. If
the fluorescent is driven with just the right frequency and the spiral is
tuned to the radar frequency it will become a AM modulated reflector. The
radar will be looking for doppler but maybe supermassive AM of the return
wave will cause it to produce that pseudo doppler harmonic in the radar
gun itself (either by intermodulation in the detector or by overriding the
FM limiter channel with too strong AM). Hmm. Is it still legal if we know
how it works or does it have to be snake oil to be legal and work ? Or
some other combination ...
