SETI Doppler searching...

I guess that the problem with doppler is like
listening for a police car, which has a wailing
rising/falling siren, (that's ET's own doppler),
coming up the main street, whilst you are on a bus
accelerating down a side street. You are
also rotating around in your bus seat (Earth's turning).
Trouble is, that you don't know what day the police
are coming, and you are deaf to most frequencies.

Additionally, the your side street is 'moving about' in relation
to the main street, and the police car's batteries are flat, so
the siren is barely discernable, and someone is playing a
trumpet on your bus! :-)
