Slow down there, Paul
Maybe I just have sour grapes, but this statement is ridiculous. And so I will ridicule it.
The radar technology... first shoots a radar beam below the surface. The beam is then reflected back, bringing with it new information about what lies beneath the soil.
If the velocity of the radar beam returned to the surface is high, soil moisture is low. If the velocity is low, soil moisture is higher.
Noo, actually, the important question is how long it takes for the radar beam to get back. The velocity of the beam in the receptor will be identical no matter where the receptor is, because that's just the way light works.
Which just goes to show you, journalists suck at quantum mechanics.
