Smart Micro Automotive RADAR Multi Sensor Systems Processing Hardware

For the many possible multi sensor applications in automotive applications, but also in robotic applications or for traffic management sensor applications a network of Radar devices may be required. Typical cases are:

 

A) switch multiple sensors together and have them measure perfectly synchronized.

B) combine the field of view beyond that of a single sensor by using sensors side by side.

C) synchronously measure in different (opposite) directions in traffic management applications.

 

Smartmicro technology is prepared for ready to run operation in a radar network, either in a master-slave setup where multiple slave sensors are connected to one master sensor.

 

Alternatively a number of Radars configured as "slaves" may report to a "master" sensor data fusion and tracking controller.

 

For the purpose of such tasks Smartmicro has developed the high performance sensor data fusion and tracking controller BUMPER-080201. It features four CAN bus ports, an Ethernet interface option, relay contacts option and has many more possibilities.

 

The BUMPER-080201 sensor data fusion and tracking controller is a robust and versatile sensor data fusion and tracking controller for UMRR sensors.

With four CAN interfaces, 10/100 Mbit/s Ethernet interface (optional), and relay output signals interface (optional) it provides a high flexibility.

Please note that in the standard configuration the device has no 120Ohms resistors on board (CAN bus termination between CAN_L and CAN_H). The resistor is nevertheless required at either end of a CAN bus and is in most cases integrated in the cable delivered along with the sensor (if cable is manufactured by Smartmicro).

I Typical values; may vary to higher or lower values depending on clutter environment. All values given for bore sight. Please note that the Radar system – like any other sensor system – although being well optimized and providing excellent performance, will not achieve a 100% detection probability and will not achieve a false alarm rate equal to zero.
II Total field of view is angle interval where reflectors can be detected; 3dB field of view is narrower.
III measured at connector; min. voltage slew rate 500V/s or max. voltage rise time 15ms; supply source impedance 0.5Ohms.
IV Also available: Ethernet, Relay contacts, see interfaces. It is recommended to use an external surge protection for power, CAN, RS485 and other interface ports.
V Interval may be adapted depending on s/w configuration and/or application specific.
