For metal detectors, the process is to cancel a part of the received signal. It's not done during transmission. Anybody?
The reflection component is in real time. Well, I don't know but it seems illogical to be able to cancel something at the exact same time it is sent out. Something does not seem right.
I am waiting to be enlightened.

Big feeding problems same like in cellular phone wireless traffic.
Answers are digital signal processing, high order digital filters, multylayer chirps and narrow band frame windows. Using 24 bit oversampling or interleaving can drastically boost wanted signals while in same time canceling terrestrial wireless feeding.
key word COLD FIRE IN DSP.
