Time Constant (TC) of targets

[Tinkerer]

Time constant of targets, TCDifferent metals have different TC’s. Even different alloys of metals have different TC’s. Jewelry gold comes in hundreds of different alloys, each with a different TC.The shape of the targets, even of similar alloy, also generates a response of different TC’s. Yet, it is...

With a traditional PI we measure the amplitude of the target response.
Much is to be gained by measuring also the target TC.
The best way to do this would be by digital signal processing. However, I found that a programmer needs to understand a function well in order to write good code...

Can we define the TAU of a target with a PI detector?

If the targets were all nicely laid out flat and there was no hot ground surrounding them, it would definitely be possible. Unfortunately this is not the way the target present themselves in the field.

Can we at least get...
