AN/MPQ-4A Mortar Locator Radar Set

AN/MPQ-4A Mortar Locator Radar Set

SYSTEM PARAMETERS

SYSTEM DESCRIPTION

The AN/MPQ-4 is a mortar locator radar set that uses a dual-beam

Power: 50 kW PEP

scanning parabolic cylindrical antenna system.

87.5 W average

HAZARD CONTROLS (to reduce or eliminate risk)

SYSTEM HAZARDS

Power Density Levels (PDL) ....

While scanning, this system is not able to produce potentially hazardous PDLs in excess

of the safety standard. While nonscanning, 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 ....

While nonscanning, exclude personnel to a distance of 40 m from the antenna.

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

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

When performing adjustments in azimuth orientation do not stand erect as not to place

oneself in the center of the main beam to eye level; approach the telescope from a

stooped position.

AN/MPQ-33 HAWK Low Power Illuminator (LPI) Radar

SYSTEM DESCRIPTION

SYSTEM PARAMETERS

The AN/MPQ-33 is a low power illuminator radar set that uses a

Frequency: 10.0 10.25 GHz

Power: 450 W

1.2 m diameter prime-fed parabolic antenna.

125 W min

SYSTEM HAZARDS

HAZARD CONTROLS (to reduce or eliminate risk)

Power Density Levels (PDL) ....

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

standard and requires a formal RFR 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, no hazard exists for personnel standing on level

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

distance of greater than 15 m and less than 55 m from the antenna.

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

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