HARACTERISTICS
Traffic radar devices have been manufactured using one of three microwave frequencies, either
the X (10.525 GHz), K (24.15 GHz), or Ka-Band (33.40-36. 00 GHz).
All of the devices emit
less than 100 milliwatts of microwave power, an amount considered by nearly all
concerned to be rather low.
Most radar units manufactured in the la st twenty years have had
emitted power in the range of 15 to 50 milliwa tts. Compared to any o ther type of radar, e.g.,
military, commercial aviation, marin e, etc., the power levels of poli ce traffic radar devices are
orders of magnitude lower. The emitted power of traffic radar de
vices is lo wer than or
comparable to other microwave or radiofrequen cy (RF) radiation-emitting devices u sed in close
proximity to persons in the general public, such as garage door openers, cellu lar telephones,
and infant monitors.
Speed control radars
are used by police in many countries. The average output power of th e
SC-300H radar system is very l
ow
and so the units are not
considered
hazardous to health, even when used in very close proximity to the body.
1. When using two-piece radar units, the antenna should be mounted so that the radar
beam is not directed toward the vehicle occupants. Although this may not be practical.
The preferred mounting location would be outside the vehicle altogether, other options,
e.g., mounting on the dashboard of the vehicle, are acceptable if the antenna is at all
times directed away from the operator or other vehicle occupants.
2. Radar antennas should be tested periodically, e.g. annually, or after exceptional
mechanical trauma to the device.
