Focus On performs a migration, which is a processing procedure that reduces or eliminates hyperbolic
diffraction patterns in the data. It removes the tails of hyperbolas to more accurately represent the center
location of a target. This makes the identification of point reflectors much easier. Migration also uses the
shape of the hyperbolas as a simple and accurate way of estimating the radar velocity (and thus dielectric)
of the material your target is in.
