Introduction
The BR-3502 radar can be used to measure the radial velocity of any moving object located in the radar
beam coverage. The output of the radar is an analog signal with a frequency and amplitude proportional to
the radial velocity and distance of the moving object.
Installation
The BR-3502 radar system includes the following two components:
• Radar antenna head
• Power supply / amplifier unit
The radar head has two (2) 1/4” mounting holes that can be used to install the head at specific locations in
your test setup. The radar head is attached to the power supply/amplifier via a two (2) meter shielded
cable which provides flexibility in positionning it for optimum results.

Safety Warning
Based on limits specified by the Federal Communication Commission (FCC) on Radio Fre-
quency (RF) emissions in a general population environment,
continued exposure to radiation
should be avoided within 0.5 meter in front of the radar. Radiation levels outside this region
fall within regulations of 1 mW/cm
2
and are not considered safety hazards. When setting up
the antenna, special care should be taken to avoid situations where the antenna radiates
towards individuals. The antenna should be positioned such that bystanders are located be-
hind the antenna. During antenna setup, the antenna power cord should be unplugged to
avoid accidental hazardous exposures to radiations. Always turn the antenna transmitter off
during periods of inactivity. Direct visual contact with the radar when transmitting should be
avoided at all times.
