Remarks:
-means sensitivity, limited by noise
It is assumed that sounding is made in a soil whose relative dielectric
permittivity is equal to 4 and specific attenuation is 1 to 2
dB/m. Depth of investigation is understood to be detection depth
of a flat boundary with reflectance equal to 1. Note that these
data are rather approximate and are strongly dependent on
parameters of the environment sounded.
