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.
