The Brigade BS-9000 radar sensor features an internal CAN interface for network connectivity, allowing the user to link up to 8 sensors and a network host on a single CAN bus, enabling monitoring of multiple detection areas around the vehicle.

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.
Object Detection 3.1 Separate Object Detection ® Each Backsense BS-9000 sensor is capable of detecting and reporting data for up to 8 objects within the limitations detailed in section 1.2. In the event that there are more than 8 objects within the detection area of a particular sensor, only the closest 8 detections will be reported, (based on object radius from sensor) 3.2 Detected Object Data The BS-9000 will transmit data for each detected object in separate CAN messages.
3.3 Detected Object Position Relative to Sensor The image below illustrates the relative position of detected objects with respect to the sensor’s front face...
Hardware Installation 4.1 Recommended Network Layouts and Limitations ® Backsense BS-9000 Systems installation must adhere to a strict network topology to ensure reliable communications between all sensors and host. The network topology must represent a bus featuring 120Ω termination at both ends. Sensors must be connected to the bus via Network Y-Cable only.
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...
4.5.4 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.
Blue 4.8 Power Input Power must be applied to the BS-9000 sensor network via a dedicated Brigade power cable. Only one power input to the system is permitted and must be suitably positioned within the network to ensure that loading from all sensors is balanced and excessive voltage drops are avoided.
5.3 CANbus Base ID All BS-9000 sensors are shipped from Brigade with a pre-set Base ID of 0x390. Messages with this ID value do not contain any detection data but do provide a Keep Alive message to the host.
Systems installers may configure sensor base ID values using their own host system, or by use of the Brigade Test tool detailed in section 7. Each BS-9000 sensor within a network must be configured with an individual Base ID. The method for Base ID configuration is simple and involves sending a single configuration message to each individual sensor in the CAN network, using a specific “Configuration ID”...

System Host 6.1 Host Responsibilities BS-9000 systems require connection to a customer-supplied host to receive and utilise object detection messages from the sensor via CAN bus. The host system is responsible for interpreting the detection data detailed in section 5.7 and applying any logic, conditioning, filtering, activation or blind zone settings (e.g.
In order for a user to configure and test the system using Brigade’s software applications they must first obtain a CANpro USB Interface from the Softing company and install drivers for this interface on their test PC.
7.5 Backsense CAN Radar Test Tool The Brigade test tool is a windows application that enables users to view all physical detection data from the radar system in real time. The test tool consists of a main Graphic & Control Window displaying a top-down view of detected objects for one selected sensor as well as a sub window for that sensor’s detection...

7.5.2 Backsense Detection Table The Backsense Detection Table is a floating sub window of the Graphic and Control window which displays numerical values for all detection data of up to 8 closest objects detected by the selected sensor. There is no user interaction available for the Backsense Detection Table. As with the detection grid of the Graphic and Control, the sensor with lowest base ID value is selected by default.
7.6 Backsense Configuration Tool The Backsense Configuration Tool is a command line type application that enables the user to perform the following functions within the BS-9000 system: Alter CAN ID of each sensor within the permitted range. • View live CAN data from the entire network. •...
