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 24 GHz ISM band (24000 MHz to 24250 MHz),
the used bandwidth is smaller than 100 MHz. The maximum transmit power is 20 dBm.

Antenna type 42 is used, consisting of one transmit and eight receive antennas, both linear
polarized. The 2 way 3 dB cut-off angle in az. +-25deg. and in el. +-5deg.
The antenna has two main lobes. The greater man lobe is at +17°, counting clockwise, the
second at -20°.

The device uses different FMCW transmit signal waveforms for distance and speed
measurement.

Please note that in the standard configuration the sensor has no 120Ohms resistor on board
(CAN bus termination between CAN_Lo and CAN_Hi and RS485 IN / OUT). 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 120Ohms 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
Tseg1:                                8
Tseg2:                                7
Tsjw:                                 1                  (SJW: synchronization jump width)

Above values for CAN bit timing are illustrated in Figure 5 used in the UMRR radar sensor
(note: the CAN module is integrated in the DSP). For comparison purposes, in Figure 6 the
CAN bit timing as defined by the CAN protocol is shown.

The CAN bit timing parts as defined by the CAN protocol (Figure 6) 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 6: CAN bit timing as defined by the CAN protocol


7.3 RS485 data interface
The RS485 interface from the UMRR sensor has a predefined speed of 230400 baud/s.
Typical other data rates are between 921.6kBit/s and 56.7kBit/s.

The RS485 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.

8 Designated use
The UMRR general purpose medium range radar is suitable for any application where the
distance to and relative radial speed of large objects has to be measured.

Typical applications are:

Robotics: measure shortest distance to obstacle.
Security: detect motions and measure distance to moving object.
Traffic management: detect moving objects, count those, measure speed and measure
distance to moving object.
Cranes: measure distance to ground.
Aircraft: measure distance to ground.

The detection range depends on object size. Very large reflectors can be detected at a range
of more than 500 m.
