Kirchoff's type representations of the DKO for the homogeneous medium prompts the general form of an integral KO:
![]() |
(99) |
where - negative weight function,
- propagation time
from
to
with accordance with a given
eiconal equation
![]() |
(100) |
Without any lack of generality we can put n=0. We propose that
![]() |
(101) |
It is well known that
It is easy to show that when point is placed behind the front
(where
is the correspondent solution of equation (100) with
condition
), then argument of
-function at
is always positive:
![]() |
