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 as
well as the angle value of each reflector inside the antenna beam are measured. 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 200MHz. The maximum transmit power is 12.7 dBm.

The antenna type 45 is used, which consists of one transmit and four receive antennas. All the
antennas are linear polarized. The two-way 3dB cut-off angle in azimuth is +-9deg and in
elevation is +-4deg.

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

6 Cables and connectors

6.1 Sensor connector
The used sensor connector is a 12-pin male (plug) circular bayonet type connector (water
proof IP67, series LF10WBRB-12PD, manufacturer Hirose, Japan). A female counterpart
(socket) has to be used to connect to the sensor. The pin numbering of the socket is shown in
Figure 6-1 and the pin description is given in Table 6-1.

Please note that in the standard configuration the sensor has no 120Ohms 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 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 interface

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 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.

7.3 RS485 data interface
The RS485 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 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.
