Project
Management

1. All
communications/
correspondence
on
network
operations
and
spectrum

management
with
the
FCC,
other
government
entities
and
other
concerned

entities
will
be
handled
through
the
Project
Manager.

2. The
locations,
call
signs
and
frequencies
of
operations
will
be
maintained
by

the
Project
Manager
and
made
available
on
request.

3. The
intent
is
to
conduct
radar
operations
with
40
km
operating
radius
from

up
to
ten
fixed
locations
in
the
DFW
Metroplex
and
to
conduct
additional

experimental
operations
from
two
mobile
locations
within
the
sixteen-‐
county
North
Central
Texas
region
(pictured
above).

Operations

1. All
radars
will
be
controlled
over
the
Internet
remotely
from
the
University

of
Massachusetts,
Amherst.

2. The
radar
operator
will
conduct
individual
system
checks
before
initiating

operations
and
health
and
status
of
radars
will
be
monitored
continuously

throughout
periods
of
operation.

3. Radars
will
be
operated
ONLY
in
anticipation
of,
and
during
severe
weather,

and
occasionally
during
off-‐operational
periods
to
allow
for
testing,

experiments,
maintenance
and
repair.

Spectrum
Use

1. All
radars
will
operate
in
X-‐band
in
the
range
9.3
to
9.5
GHz.

2. Radar
center
frequencies
will
be
offset
as
needed
to
avoid
interference

between
the
radars.

3. Emissions
labeled
as
P0N
consist
of
a
single
frequency
carrier
pulse
train

with
a
pulse
maximum
length
of
660
ns
and
a
maximum
pulse
repetition

frequency
of
2.4
KHz.
The
figure
below
shows
an
illustration
of
such
an

emission.
