AN/MPQ-49 Forward Area Acquisition Radar (FAAR) Set

AN/MPQ-49 Forward Area Acquisition Radar (FAAR) Set

SYSTEM PARAMETERS

SYSTEM DESCRIPTION

The AN/MPQ-49 is a forward area alerting radar set equipped with an IFF for

locating and identifying aircraft.

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 7.5 m from the antenna.

Exclude personnel from the shelter roof when the antenna is in its lowest operational

position.

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

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

AN/MPQ-50 HAWK Pulse Acquisition Radar (PAR\IPAR)

SYSTEM DESCRIPTION

SYSTEM PARAMETERS

The AN/MPQ-50 is the Pulse Acquisition Radar (PAR) of the

Frequency: CLASSIFIED

Power: CLASSIFIED

HAWK Air Defense System. It provides target range and azimuth

information for the system. The PAR antenna is a 1.6 x 6.7 m

cosecant-squared, prime-fed, parabolic reflector which operates in a

continuous scan only mode.

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 53 m from the antenna.

Maintain visual surveillance of the fixed-beam controlled zone. Exclude personnel from

the shelter roof when the antenna is in its lowest operational position.

Open/cracked waveguides .......

All open waveguides and the feed horn aperture produce potentially hazardous PDLs

within 1.0 m. Exclude personnel from these areas and do not permit operation of this

system with any cracked, broken or open waveguide. Exclude personnel from the area

on top of the PAR antenna, between the antenna feed and the reflector.

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

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

The stabillitron tube in the transmitter circuit can produce X-radiation.
