Given the few responses to date, I¹ll fess up to cluelessness and curiosity. Aside from the obvious dynamic range limitation working in the time domain, if you limit yourself to the time domain, how do you map SE vs. frequency?
And given the inherent wide band nature of a TDR signal, I can¹t see it being radiated properly. I¹m thinking you would have to use something like an ASTM 4936 coaxial test fixture in order to main signal integrity up to the reflection point where the sample material puck is installed.

The simplicity is tempting but I am dubious about the dynamic range? I have poked about in the usual place but didn¹t find any definitive studies. (I suppose that is a clue in and of itself!)
