AN/FPS-71 Radar Set

AN/FPS-71 Radar Set

SYSTEM DESCRIPTION

SYSTEM PARAMETERS

The AN/FPS-71 is a radar system that is interlocked such that with the antenna

stationary, the set is operated at reduced power.

HAZARD CONTROLS (to reduce or eliminate risk)

SYSTEM HAZARDS

Power Density Levels (PDL) ....

At full power and while scanning, this system is able to produce PDLs in excess of the

standard. Establish a Nonionizing Radiation Protection Program (IAW guidelines

provided in this TB) .

Hazard distance from antenna ....

Exclude personnel to a distance of 85.4 m from the antenna.

Open/cracked waveguides .......

The area between the feed and the reflector and any open waveguide produce potentially

hazardous PDLs. Periodically inspect waveguides for cracks or leaks and replace

suspect waveguides.

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

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

There is a potential x-ray hazard inside transmitter cabinet. Instruct personnel to operate

system only with transmitter cabinet doors closed.

SYSTEM HAZARDS

HAZARD CONTROLS (to reduce or eliminate risk)

Power Density Levels (PDL) ....

This system is not able to produce potentially hazardous PDLs in excess of the safety

standard.

Open/cracked waveguides .......

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

Exclude personnel to a distance of 6 cm from any open waveguide.

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

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