INTRODUCTION

• This document is a short documentation of the general purpose universal medium range radar (UMRR) UMRR-12 Type 48 radar sensor with type 48 antenna.

GENERAL DESCRIPTION

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.

TRANSMIT SIGNAL

• The UMRR transmit frequency is in the 24 GHz ISM band (24000 MHz to 24250 MHz) and the used bandwidth is less than 250MHz. The maximum transmit power is 12.7dBm.
• Antenna type 48 consists of 2 TX antennas with same antenna characteristics but different center position on the board and 8 uniform RX antennas. The TX antenna have a 3dB antenna beam width of +-34° in azimuth and +-6,5° in elevation. The 8 RX antennas have a 3dB antenna beam width of +-25° in azimuth and +-7° in elevation. Highest TX antenna sidelobe: @+74°, highest RX sidelobe at +-50°.
  Note: max. Gain for TX antenna at azimuth angle +-22°, elevation angle 0°. The RX antennas have max. gain at boresight.

Gain RX: 11.1 dBi.

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

GENERAL PERFORMANCE DATA

• After power up or reset, the sensor readings are within specified performance within 60 seconds.
• At the first starting stage within 35 seconds, another waveform will be initialized before it switches to Waveform 6.

HARDWARE

UMRR SENSOR

An example picture of a UMRR (universal medium-range radar) sensor (housing type 070707) is shown in the figures below

SENSOR DIMENSIONS
All values given in mm.

CABLES AND CONNECTORS

SENSOR CONNECTOR

• The 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), e.g.
• LF10WBP-12S, is used to connect to the sensor. The pin numbering of the socket is shown in Figure 6 the pin description is given in Table 6-1.

• Please note that in the standard configuration the sensor has 120 Ohms resistor on board (CAN bus termination between CAN_L and CAN_H).
• 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.

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.

CAN-SETTINGS

• Baud Rate: 500 kBit/s or lower

• Tseg1: 8

• Tseg2: 7

• Tsjw: 2 (SJW: synchronization jump width)

• Above values for CAN bit timing are illustrated in Figure 7 used in the UMRR radar sensor (note: the CAN module is integrated in the DSP). For comparison purposes, in Figure 8 the CAN bit timing as defined by the CAN protocol is shown.

• The CAN bit timing parts as defined by the CAN protocol (Figure 8) 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.

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.

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.
