1 Introduction
Brigade’s Backsense®uses FMCW (Frequency Modulated Continuous Wave) radar system
technology to detect people and objects in blind spots, significantly reducing collisions.
Backsense®detects both stationary and moving objects, providing the driver with in-cab visual
and audible warnings. Backsense®works effectively in harsh environments with poor visibility
including darkness, smoke, fog, and dust.
It is imperative that any Brigade Backsense®system is fitted and commissioned by competent
and trained technicians. The installer is responsible for the fitness for purpose of the overall
system and must adhere to relevant regulations and legislation. Operators of the vehicle or
machine to which the Brigade Backsense®System is fitted must be made fully aware of how
to interpret the system so they will not be distracted by or rely completely on it. Distraction can
cause collisions.
The system is intended as an aid only. The operator must still concentrate on operating the
vehicle, obeying traffic and local regulations. Vehicle or machine operators must continue to
use their own training, senses, and other vehicle aids, such as mirrors, as if the system were
not in place. Nothing removes the responsibility of the operator to operate the vehicle in a
proper and lawful manner.

1.2 Object Detection Capability
Warning
•There is no detection of objects or part of an object closer than approx. 0.3m to
the sensor.
•The Brigade Backsense®radar beam has a 140° horizontal angle out to the maximum
designated width. The vertical angle is 16°. Both angles are symmetrically perpendicular
to the sensor front surface.
•All dimensions for detection of objects are nominal and vary significantly depending on
many parameters. For more details, see section “1.2.2 Factors Influencing the Detection
of Objects”.
•An object will cause a detection alert in less than 0.1 second, subject to object
properties and proximity.
•After turning on the power the system takes around 6 seconds to be active. Time from
standby to active state is less than 0.6 second.

Notes:
•For distances below 1.5m (detection with relative speed only) or below 0.3m (no
detection) the space covered in general by radar systems is very small. In this scenario,
Backsense® may not be the most suitable solution; therefore, Brigade recommends
adding an additional or alternative detection system depending on the vehicle’s
application. For example, Brigade Backscan®, based on ultrasonic sensing technology,
offers superior detection at close ranges.
•Brigade Backsense®system is not affected if multiple systems are operating in the same
area or on the same vehicle, even if they are installed in close proximity with overlapping
detection ranges.
•Independent detection of target objects can be achieved when there is a minimum range
separation of 0.8m and velocity difference of >0.7m/s between each.
Tip: Brigade Backsense®detection is generally better when there is relative speed
between the sensor and the objects and when the direction of approach is
perpendicular to the sensor front face.

1.2.2 Factors Influencing the Detection of Objects
Brigade Backsense®shares in principle the advantages and limitations of all radar-based
systems when compared to other sensing technologies. In general, it can reliably detect most
objects in most environmental conditions such as dirt, dust, rain, snow, sun, fog, darkness,
acoustic noise, mechanical vibration, electromagnetic noise, or similar.
However, there are some occasions when an object could stay undetected. Radar works on
the principle of line of sight and relies on some of the electromagnetic energy transmitted by
the sensor being reflected from the object to the sensor. If an object does not reflect enough
electromagnetic energy back to the sensor it will not be detected.
In the case where there are multiple objects in the detection area at various distances and/or
angles, the sensor detects the closest object, which is the most important one for collision
avoidance.
The object properties, location and direction are key influences in determining if an object is
detected or not. The influencing factors are listed below.
•Size: Larger surfaces are detected better than smaller surfaces. If there are small and large
objects in front of the sensor, the smaller object might only register in Detection Zones
closer to the sensor and may be subjected to the limitations detailed in section “1.2 Object
Detection Capability”, paragraph “Notes”).
•Material: Metal is detected better than other materials, e.g., wood, plastic.
•Surface: A smooth and solid surface is detected better than rough, uneven, porous,
fragmented or liquid surfaces, e.g., bushes, brick work, gravel, water.
•Shape: A flat object is better detected than a complex shape. Variation in relative location
and direction can influence detection significantly.
•Angle: An object facing directly towards the sensor (perpendicular, orientation head on to
the sensor) is detected better than an object that is located towards the edges of the
detection area or at an angle.
•Distance: An object closer to the sensor is better detected than one that it is further away.
•Relative speed to sensor: Detection is better if there is a relative speed between object
and sensor.
•Ground condition: Objects on flat, mineral material ground are better detected than on
rough or metal surfaces.

6
•Environmental conditions: Dense dust or very heavy rain or snowfall will reduce the
detection capability.

3 Hardware Installation
3.1 System Connectivity

BS-7100 (7248)
BS-7100-IG (7523) V1.0 ENG
3.2 Installation Site
The installation site must be larger than the detection range of the intended Backsense®
System and should be relatively flat without excessive deviation. This will allow for basic
setup, configuration, and testing of the Backsense®system.
3.3 Electrical Connections
Refer to the vehicle manufacturer or bodybuilder guidelines for installation procedures and
connectivity in all applications. Ensure the positive supply connections are fused at the source.
The system connections are shown in the table below:
•Red cable to non-permanent power supply e.g., ignition.
•Black cable to ground.
•Grey cable to the activating trigger, e.g., reverse. This Activation Input changes the
system status between standby and active.
•White cable is a trigger output to activate secondary functions or devices. The white cable
is switched to ground (black cable) when an object is detected within the detection area.
For example, a secondary device could be a Brigade bbs-tek®white sound®alarm or a
light beacon to send a warning into the detection area. Simply connect the device to the
same non-permanent power supply as the red cable is connected to and use the white
cable as a negative connection. For electrical loading limits see section “6 Specifications”.
On the BS-7100 system, the distance when the trigger output is activated can be
configured.

3.4 Sensor Mounting and Location
3.4.1 Sensor Direction
The sensor should be mounted in an upright position with the cable exit on the sensor pointing
downwards, such that the Brigade logo on the front of the sensor is readable when standing in
the required detection area. The front of the sensor should have line of sight to all areas where
objects should be detected.
3.4.2 Sensor Fixing
The unit is supplied with four M5x30mm screws and four M5 polymer locknuts for mounting
purposes. The recommended torque is 6Nm or 50 inch/lbs.
3.4.3 Vehicle Overhang into Detection Area
It is recommended that the mounting position on the vehicle should avoid any vehicle furniture
overhanging into the detection area, as such objects will cause false alarms (for exceptions
refer to section “1.2 Object Detection Capability”, paragraph “Warning”).
The detection area of the Brigade Backsense®radar beam has a 140° horizontal angle to the
maximum designated width and a vertical angle of 16°, see section “1.2.1 Detection Pattern”
for details.
