AN/MPQ-46 HAWK High Power Illuminator (HIPIR) Radar

AN/MPQ-46 HAWK High Power Illuminator (HIPIR) Radar

SYSTEM DESCRIPTION

SYSTEM PARAMETERS

The AN/MPQ-46 is a high power illuminator radar set.

Frequency: CLASSIFIED

Power: CLASSIFIED

HAZARD CONTROLS (to reduce or eliminate risk)

SYSTEM HAZARDS

Power Density Levels (PDL) ....

This system is able to produce potentially hazardous PDLs in excess 5x the safety

standard and requires a formal RFR protection program to ensure its safe use. Establish

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

Hazard distance from antenna ....

When the elevation angle is positive (+ 0 mils), no hazard exists to personnel on level

ground. When the elevation angle is minimal (-200 mils), exclude personnel to a

distance of greater than 15 m and less than 112 m from the antenna.

Open/cracked waveguides .......

All open waveguides and loose or open flanges produce very hazardous PDLs within

close proximity of the break. Exclude personnel to within 2.2 m from a fully open

guide at the transmitter. 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.

Shelters erected around this equipment may cause potentially hazardous reflections of

RF energy. Post areas accordingly.

AN/MPQ-48 HAWK Improved Continuous Wave Acquisition Radar (ICWAR)

SYSTEM DESCRIPTION

SYSTEM PARAMETERS

The AN/MPQ-48 is a continuous wave radar set of the HAWK

Frequency: CLASSIFIED

Power: CLASSIFIED

Air Defense System.

HAZARD CONTROLS (to reduce or eliminate risk)

SYSTEM HAZARDS

Power Density Levels (PDL) ....

In the nonscanning 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). In the scanning mode, this system is not able to

produce potentially hazardous PDLs in excess of the safety standard.

Hazard distance from antenna ....

In the nonscanning mode, exclude personnel to a distance of 21 m from the antenna.

With the antenna positioned at a fixed positive elevation angle, no hazard exists for

personnel on level terrain.

Open/cracked waveguides .......

All open waveguides and loose or open flanges produce potentially hazardous PDLs.

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.
