1 Introduction
Brigade’s Backsense®uses FMCW (Frequency Modulated Continuous Wave) radar system
technology and is designed to detect people and objects in blind spots, significantly reducing
collisions. Backsense®detects both stationary and moving objects and works effectively in
harsh environments with poor visibility including darkness, smoke, fog and dust.
Backsense®On Screen Display system combines object detection information from Brigade’s
BS-9000 radar sensors with images from Backeye®camera and monitor systems, providing
the driver with in-cab visual and audible warnings overlaid on to camera images on-screen.
This combination of object detection warnings and video images allows the machine operator
to view all pertinent information in a single location reducing the number of systems he would
otherwise need to monitor.
The Backsense®OSD-022 ECU is capable of connecting to up to 2 BS-9000 radar sensors
and up to 2 Backeye®cameras. The system is fully configurable to enabling a range of
Radar/camera implementations.
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 or machine, 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 or machine in a proper and lawful manner.
1.1 Detection Range
Backsense®detection range is fully configurable enabling customisation to suit a multitude of
applications Minimum and maximum limits for detection range are detailed in the table below:

Additional detection, blind and alerting parameters are configurable within the system
including: Detection Zone length Blind Zone width, Blind Cell activation, Trigger Output lengths
and Audible Alert starting zones. Blind Zone length is fixed. Refer to section 5.3 for more
information.

1.2 Object Detection Capability
Warning
•There is no detection of objects or parts of an object closer than approx. 0.3m to
the sensor.
•Object detection between approx. 0.3m to 1.3m from the sensor requires a
minimum relative speed of around 2km/h between the object and sensor. The same
requirements apply for re-detection of objects after a stationary condition.
•Brigade Backsense®radar beam angle has a 120° horizontal angle out to the maximum
designated width and symmetrically perpendicular to the sensor front surface. The
vertical angle is 12°.
•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 0.5 seconds.
•After application of power, the system takes around 9 second to complete the power up
routine as detailed in section 4.1. Time from standby to active state is less than 0.5
seconds.
Notes:
•For distances below 1.3m (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 and 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®systems remain unaffected when multiple sensors are operating in
the same area or on the same vehicle. Close proximity and overlapping detection areas
cause no adverse effect on Backsense’s detection properties.
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 back 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 will detect up to 8 of the closest objects (based on radius), which are the
most important 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 the detection area, the smaller object might only register in Detection Zones closer
to the sensor.
•Material: Metal is detected better than non-metal 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.
•Environmental conditions: Dense dust, heavy rain or snowfall will reduce the detection
capability.

3 Hardware Installation
3.1 System Connectivity
The diagram below shows the recommended setup for Brigades BS-9001-OSD system. Other
system configurations are possible depending on the application.

9
3.2 Installation Test Site
The system test site should be relatively flat without excessive deviation and must be larger
than the detection range of each sensor in the intended Backsense®system. This will enable a
basic setup, configuration and testing of the installed system.
3.3 BS-OSD-022 ECU Installation
The Backsense®ECU must be installed in a dry location inside the vehicle cabin, close to the
monitor used with the system. If the vehicle cabin is liable to ingress of liquids or other foreign
objects which could damage to the ECU, then a protective enclosure should be fitted or other
steps taken to avoid such damage.
The ECU may be installed in any orientation but must be mounted to a flat surface using a
minimum of 4 fixings. The sides of the ECU enclosure feature re-enforced, slotted flanges
designed to accept an M5 screw. Suitable washers must be used under screw heads to
spread the load and avoid damaging the mounting flange.
ECU USB cable must be accessible for configuration purposes. The cable and plug should be
protected after configuration so that no debris can enter and no it cannot become damaged
during machine operation.
3.4 Camera and Monitor Installation
Backsense®BS-OSD-022 has been designed to work in conjunctions with Brigade’s Elite
range of camera and monitor systems however installation may vary depending upon
equipment selection. The monitor should be mounted so the vehicle operator has good
visibility in all environments and situations. The monitor should be fixed in a suitable location in
line with any current legislation/regulations.
Refer to the Installation guidelines for the chosen equipment to ensure that best practices are
followed. Any unused connectors on the ECU must be suitably insulated to protect against
ingress of liquids or other foreign objects which could cause damage.
3.5 Sensor Mounting and Location
3.5.1 Sensor Direction
Each sensor should be mounted in an upright position with cable exit on the sensor pointing
downwards. The Brigade logo on the front of the sensor should be in readable, normal
orientation when standing in the required detection area, see image above. The front of the
sensor should have line of sight to all areas where objects should be detected.

3.5.2 Sensor Fixing
Each unit is supplied with four M5x30mm screws and four M5 polymer locknuts for mounting
purposes. The recommended torque is 6Nm or 50 inch/lbs.
3.5.3 Vehicle Overhang into Detection Area
The vehicle mounting locations should avoid detection of any overhang or furniture where
possible. Such objects will cause false alarms (for exceptions see section 1.2, “Object
Detection Capability”, paragraph “Warning”). The detection area of the Brigade Backsense®
radar beam has a 120° horizontal angle to the maximum designated width and a vertical angle
of 12°, see section “1.2.1 Detection Pattern” for details.
The system can be configured using the Blind Area setup to ignore objects in the detection
area, see section for 5.3.8 details.
3.5.4 Mounting Angle
Brigade recommends mounting the radar sensors on brackets (available from Brigade, see
section 2.2), which can be adjusted for angle in the horizontal plane, enabling performance
optimisation. See below for suggested vertical angle vs sensor installation height on the
vehicle.
Depending on the vehicle, working environment and typical objects to be detected an
adjustment of a few degrees around the suggested values can improve the detection
performance or avoid false alarms.

3.5.5 Offset to Vehicle Centre Line Mounting
If the Brigade Backsense®System is fitted off-centre or at an angle to the vehicle centre line
the detection area (see section “1.2.1 Detection Pattern”) is likely to be incorrect or misaligned
with the vehicle width or direction of travel.
Using the Blind Zone configuration might resolve or compensate for mounting location issues,
enabling off-centred or angled installations, see section 5.3.8 for details.
3.6 System Cables
Cables should be run in conduit and along suitable cable runs throughout the vehicle. A 24mm
hole is required to pass the BS-9000 Radar sensor connectors through.
Note: ●Allow a reasonable bending radius when folding excess cabling or for the routing of
the cable.
•Avoid tight bends close to the connectors.
•Avoid pulling on the connector.
•Ensure all cables are fitted into suitable protective conduit
•Ensure cabling and connectors are fitted away from sources of excess heat, vibration,
movement and water or dirt.
