Raytheon Request for Special Temporary Authorization
STA File Number: 0043-EX-ST-2016
1/12/2016

Purpose of Operation:
Frequency authorization is being requested to test the performance of six commercial maritime radars.
Radars of similar type will be tested together in two different groups; three large fixed site radars and
three smaller shipboard radars.

Technical Synopsis:
- Spectrum requested: 9200 – 9500 MHz
- Ten frequencies will be selected from the spectrum granted for each test group
- Power levels requested: 770 kW ERP
- Expected time of use: Between 0000 and 2400, 12-16 hours/day
- Stop buzzer contact: Peter Scarlett (Cell: 519-572-4394)

STA Explanation:
The Special Temporary Authorization is required to quantify the performance of the radars under test in a
short time frame in order to meet contractual obligations. This testing will take place as early as 2/4/2016.

Radar Mounting and Direction of Operation:
The radars will be operated from the parking lot of the Holiday Inn, Ponce, Puerto Rico for up to 10 days.
They will be mounted on the roof of a small container or other temporary mounting structure at
approximately 10 ft above ground level. The antennas are 8 - 21 foot long slotted waveguide with gains
of 30 – 38 dBi, and will be mounted close to the roof surface. The radars rotate clockwise between 15 -
30 rpm and will only transmit towards the sea at azimuths between 180 and 270 degrees. Radars of
similar type will be tested together in two different groups; three large fixed site radars and three smaller
shipboard radars. Ten frequencies are required for each test group.

RF Hazard Calculations and Site Safety Measures:
Initial calculations show that power density will fall below general public exposure limits at less than 2.3
meters distance and occupational exposure limits at less than 1.1 meter, using formula (7) from FCC
OET Bulletin 65 “Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency
Electromagnetic Fields”, dated August 1997. These calculations take into account the highest duty factor
and the rotating antenna duty factor.

A safety interlock disables the transmitters unless the antenna is rotating. The radars will be operated in
a fenced guarded area at all times.

Raytheon’s RF safety group is involved in all testing that requires free space radiation to ensure that no
personnel are subjected to RF power density levels exceeding the Maximum Permissible Exposure
(MPE) limits of the Part 1.1310 of the FCC Rules and the guidelines in FCC’s OET Bulletin Number 65.

List each type of emission separately:
There are two Terma radars that require six frequencies each. The other four radars only require two
frequencies each. Each radar test group requires a total of ten frequencies. Frequencies will be selected
to prevent inter-radar interference. The radar’s operate similarly. Their transmit waveform is a fixed
sequence of short, medium and long chirp pulses alternating between low- and high-band frequencies
that are approximately 120 MHz apart. The pulse repetition frequency is either 1500 or 2000 Hz.

All pulses have an FM chirp bandwidth of 32 MHz or 20 MHz with a 100 nsec rise-time and differ only in
their pulse duration and necessary bandwidth as shown in Table 1 above. The emissions are Q3N.

The spectrum required for each test group in the 9.2 – 9.5 GHz band is summarized in Table 2 below.

Necessary bandwidth. Explain how determined.
Using the necessary bandwidth formula for FM-pulsed radars from the NTIA Manual, with a 0.1 μsec rise
time:




Where
        t = Emitted pulse duration at 50% amplitude (voltage) points. The 100% amplitude point is the
             nominal peak level of the pulse.
        tr = Emitted pulse rise time in μsec from the 10% to the 90% amplitude points on the leading
             edge.
        Bc = Bandwidth of the frequency deviation (the total frequency shift during the pulse duration) in
             MHz

Location:
The radar will be located in the rear parking lot of the Holiday Inn, Ponce, Puerto Rico, within 150 meters
of the coordinates below. The address is 3315 Ponce Bypass, Ponce, Puerto Rico, 00731.

The coordinates of this address are: Latitude 17° 58' 42.2" N, Longitude 66° 40' 17.8" W.
