AN/UPQ-3 Improved GUARDRAIL

AN/UPQ-3 Improved GUARDRAIL

SYSTEM PARAMETERS

SYSTEM DESCRIPTION

The AN/UPQ-3 consists of a Ground Tracker and an Airborne WideBand

Frequency: 9.6 9.95 GHz/

Data Link. The Ground Tracker utilizes a 1.8 m diameter cassegrain

14.5 15.5 GHz (Ground Tracker)

antenna and the Airborne Band utilizes a 20 cm diameter parabolic

15 15.35 GHz ( Airborne Band)

antenna.

Power: 70 W (Ground Tracker)

70 W (Airborne Band)

HAZARD CONTROLS (to reduce or eliminate risk)

SYSTEM HAZARDS

Power Density Levels (PDL) ....

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 Ground Tracker nonscanning mode, exclude personnel to distances of 12 m from

the antenna. In the Airborne Band, exclude personnel to distances of 6 m from the

antenna.

Open/cracked waveguides ........

All open waveguides and the antenna radome produce potentially hazardous PDLs.

Exclude personnel to a distance of 50 cm from the antenna radome. Periodically inspect

waveguides for cracks or leaks and replace suspect waveguides.

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

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