AN/TPN-18A Radar Set (utilized in AN/TSQ-71, AN/TSQ-72)

SYSTEM DESCRIPTION

SYSTEM PARAMETERS

The AN/TPN-18 is a transportable radar system used at airstrips

Frequency: 9 9.6 GHz

Power: 192 W average

and heliports for air traffic control and ground control approach

200 kW PEP

of aircraft. This system utilizes an azimuth and elevation

antenna configuration.

HAZARD CONTROLS (to reduce or eliminate risk)

SYSTEM HAZARDS

Power Density Levels (PDL)...

In the scanning mode, this system is not able to produce potentially hazardous PDLs in

excess of the safety standard. In the non scanning mode, this system is able to produce

potentially hazardous PDLs in excess of the safety standard. Establish a Nonionizing

Radiation Protection Program (IAW guidelines provided in this TB) .

Hazard distance from antenna.

In the nonscanning mode, exclude personnel to a distance of 25 m from the azimuth

antenna and 11 m from the elevation antenna. Do not operate main beam in potentially

occupied areas.

Open/cracked waveguides......

All open waveguides and feed horn outputs produce potentially hazardous PDLs within

close proximity. Exclude personnel from these areas and check waveguide portion of this

system periodically for breaks or cracks, and replace any suspect waveguide.

Other..............................

Consult the equipment Technical Manual for other operator and/or maintenance hazards.
