ABSIBACX_
The
electrical
resistivity
of
the
ground
can
be
measured
by
several
methods.
One,
which
has
proven
useful,
is
the
controlled
source
magnetotelluric
method
(CSAMT).
Current
over
a
wide
range
of
frequencies
is
introduced
into
the
earth
through
a
grounded
dipole.
Then
the
resulting
electric
and
magnetic
fields
are
measured
at
a
distance
greater
than
several
skin
depths.
The
apparent
resistivity
is
then
calculated
by:
p
=l/5f
[E/B]
2
.
The
apparent
resistivity
vs.
frequency
can
be
converted
into
true
resistivity
vs.
depth.
This
grant
involved
an
investigation
into
the
HAARP
virtual
antenna
pattern
out
to
200
km,
and
its
use
as
a
CSAMT
transmitter.
