RF Safety

The FOD Finder™ XFV2 radar transmits RF power at 78-81 GHz out of a radome making up
the front face of the radar enclosure. The MMW energy travels thru the white face
plastic, where it diverges at an angle of approximately 120 degrees in azimuth and 1
degree in elevation. Over a sweep period of approximately 50ms, this fan beam is swept
over a range of 4 degrees in elevation.
The FCC Maximum Permissible Exposures (MPE) for this operating frequency are a power
density of 5mW/cm
2
averaged for a time duration of 6 minutes max for and operator and
1mW/cm
2
averaged for a time of 30 minutes max for the general public.
When working with this product powered up, the operator should not stand in front of
the unit, any closer than 20 cm from the radome where the radar beam is emitted.
When the unit is installed where the General Public may be exposed to the radar beam
we suggest the general Public should be kept away at a distance greater then 3 meters
from the front of the radar where the beam is emitted. At this distance, the exposure
level is .005 mW/cm
2
, or 0.5% of the MPE threshold.
