Flattening is intended for rebuilding initial profile into the profile with flat
horizontal interface depicted by Annotation/Lines or Annotation/Picket.
Fig. 11.7. Example of using the flattening procedure.
Left-hand: initial profile; right-hand: resulting profile.
Zeroline flattening is used to flatten the direct surface wave in the whole profile,
what could be used to decrease effect of transmitter electronic heating or antenna
lifting changing.
Migration – reconstruction of original shape of underground interface and local
objects by its radiolocation profile. Very effective when having diffracting objects
underground utilities, fixtures) on the profile. Software provide migration methods
Stolt (F-K) method and Hyperbolic summation .
Fig. 11.8. Example of migration procedure using.
Left-hand: initial profile; right-hand: resulting profile.
Envelope used to obtain signal envelope by Hilbert transform and works along the
trace. The algorithm used here includes four stages: application of FHT (fast Hartley
transform) for transition from the time to the frequency domain, Hilbert transform,
