If you need to ask that question....then you don't know about GPR. That means once again you're pretty much wasting my time.
Actually, having studied Physics at University and having volunteered on a few archaeological digs in the UK I know a fair amount about Ground Penetrating Radar.
For example, I know that in ideal conditions GPR can reach a depth of about 10m, but at that limit it is only really good at detecting large structures. GPR is very limited by clays (high conductivity of the soil causes signal loss) and rocky soils (rocks cause the signal to be dispersed), often limiting the maximum depth to less than 2m.
One of the key things about GPR is that it really only gives you an indication of an "anomaly", so if you really want to know what it is you have to actually dig to confirm what it is. i.e. Something that looks like it might be a grave cut could turn out to be nothing more than an old rotten tree stump (as happened at a dig I once worked on).
So, let's try the questions you tried to ignore again:
What technology are they using to penetrate deep into the soil? And how deep exactly?
Do you have a link to the paper that they published detailing their discoveries?
Oh, and one more: what is the name of the lead archaeologist?
