4 General description
4.1 Sensor description
The main task of the UMRR is the detection of any reflectors in the field of view, to measure
the distance, the relative speed and the angle to the shortest reflector (and to other
reflectors), to detect motion and to track (filter) the results over time.

For this general purpose measurement application, range and relative radial speed and
the angle value of each reflector inside the antenna beam are measured and the results are
reported via the communication links cycle by cycle.
4.2 Transmit Signal
The UMRR transmit frequency is located in the 76 GHz to 77 GHz band, the used bandwidth
is smaller than 1 GHz. The maximum transmit power is smaller than 55dBm.
The UMRR-11 sensor type 132 provides 2 modes, AEB- and ACC-mode. Antenna type 132 is
used, consisting of three transmit and four receive antennas, both are linear polarized. The 2
way 3 dB cut-off angle by AEB-mode in azimuth is ± 25 deg. and in elevation is ± 4.1 deg.
The 2 way 3 dB cut-off angle by ACC-mode in azimuth is ± 7 deg. and in elevation is ± 4.1
deg.
The device uses different FMCW transmit signal waveforms for distance and speed
measurement.

Please note that in the standard configuration the sensor has no 120 Ohms resistor on board
(CAN bus termination between CAN L and CAN H). The resistors are nevertheless required at
either end of a CAN / RS485 bus and is in most cases integrated in the cable delivered along
with the sensor (if cable is manufactured by Smartmicro).
For the RS485 data interface there is a 120 Ohms resistor on board of the sensor.
A number of cable sets for initial operation and test purposes are offered by Smartmicro, to
deliver a fast set-up of a sensor system. Among those preconfigured ready-to-run cables as
well as cable stumps (pig tail cables or various lengths) which carry the connector on one
side and open wires on the other.

7 Data interfaces
7.1 CAN data interface
This specification gives a detailed description of the CAN data communication used in the
UMRR based systems on the sensor CAN. The UMRR is compliant with CAN 2.0B standard.

CAN is a very robust full duplex bidirectional interface.
7.2 CAN-Settings
Baud Rate:                            500kBit/s or lower
Prescalar:                            1
Tseg1:                                8
Tseg2:                                7
Tsjw:                                 2                  (SJW: synchronization jump width)

Above values for CAN bit timing are illustrated in Figure 7-1 and used in the UMRR radar
sensor (note: the CAN module is integrated in the DSP). For comparison purposes, in Figure
7-2 the CAN bit timing as defined by the CAN protocol is shown.

The CAN bit timing parts as defined by the CAN protocol (Figure 7-2) can be described as
follows:
      • Sync: This part of bit time is used to synchronize the various nodes on the bus. An
         edge is expected to lie within this segment. For the UMRR sensor, this segment is
         always 1 TIME QUANTUM (TQ).
      • Prop: This part of the bit time is used to compensate for the physical delay times
         within the network. It is twice the sum of the signal’s propagation time on the bus
         line, the input comparator delay, and the output driver delay. For the UMRR sensor,
         this segment is programmable from 1 to 8 TIME QUANTA (TQ).
      • Phase 1: This phase is used to compensate for positive edge phase error. For the
         UMRR sensor, this segment is programmable from 1 to 8 TIME QUANTA (TQ) and
         can be lengthened by resynchronization.
      • Phase 2: This phase is used to compensate for negative edge phase error. For the
         UMRR sensor, this segment is programmable from 2 to 8 TIME QUANTA (TQ) and
         can be shortened by resynchronization.

                            Figure 7-2: CAN bit timing as defined by the CAN protocol


7.3 RS-485 data interface
The RS-485 interface from the UMRR sensor has a predefined speed of 115200 baud/s.
Typical other data rates are between 921.6kBit/s and 56.7kBit/s.

The RS-485 message payload is identical to the CAN format. The data messages will be sent
in several packets of one byte.

Every cycle begins with a start sequence and ends with a calculated checksum and an end
sequence. The length of the data payload depends on the number of targets and tracked
objects.
Every cycle has one start sequence one end sequence and one checksum.

Every data message consists of its own message ID, the number of used data bytes and the
data bytes itself.
The checksum is calculated on all data except the start sequence and the end sequence. The
Checksum is a simple XOR Assignment of all n data bytes.
Byte0 XOR Byte1 XOR Byte2 ... XOR Byte (n-1)

7.4 Transceiver schematics
In Figure 7-3 and Figure 7-4 the exact DSP board schematic of the UMRR is given. The CAN
pins of the Co-Processor are connected to a CAN transceiver, which is connected to the pins
CAN1_P and CAN1_N. Similarly, the RS485 pins of the Co-Processor are connected to a RS485
transceiver,   which     is    connected    to    the    pins     RS485_TX_ETHRN_TX4_P,
RS485_TX_ETHRN_TX4_N, RS485_TX_CAN2_ETHRN_TX3_P, RS485_TX_CAN2_ETHRN_TX3_N.
The Ethernet-Phy is connected to an Ethernet transformer, which is connected to the pins
ETHRN-TX1_P, ETHRN-TX1_N, ETHRN-TX2_P, ETHRN-TX2_N.

8 Applications
It can be used for long and medium range collision warning (CW), adaptive cruise control
(ACC) applications in autonomous driving systems.

One or multiple sensors are specifically integrated into vehicle models of automotive OEMs.
Usually there is a certain OEM-specific engineering effort required for the adaptation to
specific vehicle models and the test and qualification procedures to be applied. Customer
specific connectors, CAN(FD)/Ethernet interfaces, tracking algorithms, warning algorithms or
other custom software packages can be included.

Some examples of application in automotive fields are shown as follows:
- Adaptive cruise control (ACC)
- Advanced emergency braking (AEB)
- Forward collision warning (FCW)
- Rear collision warning (RCW)

This sensor can optionally be compliant to ASIL Level B in customer specific projects
(requirements and safety concept to be agreed between OEM and smartmicro). It can also
be offered with AUTOSAR compliant software in customer specific projects (specification to
be agreed between OEM and smartmicro).

9 Declaration of Conformity
9.1 Declaration of Conformity for USA
This device has been tested and found to comply with the requirements set forth in 47 CFR
Part 95, Subpart M for both fundamental emissions and unwanted emissions. These limits
are designed to provide reasonable protection against any harmful interference when the
device is operated in a commercial environment.

Modifying the device without smartmicro’s authorization may result in the device being no
longer compliant with FCC requirements. In that event, your right to use the device may be
limited by FCC regulations, and you may be required to correct any interference to radio or
television communications at your own expense.

Changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the device.

This device complies with the requirements set forth in 47 CFR Section 95.3385 addressing
RF exposure from radio frequency devices. To maintain compliance, the minimum separation
distance from the antenna to general bystander is 20 cm.
