Safety Warning
Based on limits specified by the Federal Communication Commission (FCC) on Radio Frequency (RF) emissions in a general population environment,
should be avoided within 0.5 meter in front of the radar. Radiation levels outside this region
fall within regulations of 1 mW/cm
!
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 behind 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.

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.
Operation
The BR-3502 is powered on 120/240 VAC, 50-60 Hz using a conventionnal power cord for connection
in standard power outlet. It is interfaced to a processing unit using a single four-wire cable equipped with
military connectors. This cable is used to carry the radar doppler signal to the processing unit and the
antenna transmission control. You should connect your radar cable from this connector to the appropriate
radar input on your processing unit.
The connector type is ITT Cannon MS3124E16-8P. The following table discribes the pinout of this connector:
Pi n Function
A Not Connected
B Not Connected
C Not Connected
D Remote Make for Antenna Transmitter Control (+ 5 Vdc Output)
E Make Ground
F Doppler Signal + (5 Vpp max.)
G Doppler Signal - (5 Vpp max.)
The remote activation of the transmitter is done by the processor by short circuiting pins D and E of the
connector. When the antenna interface cable is not connected, the rad ar unit does not transmit.
