User Manual / Functional Description of the test equipment (EUT)
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 located in the 24 GHz ISM band (24000 MHz to 24250 MHz), the used
bandwidth is smaller than 250 MHz. The maximum transmit power is 12.7dBm. Antenna type 40 is used,
consisting of one transmit and two receive antennas, both linear polarized. The 2 way 3 dB cut-off angle in az.
±6deg. and in el. ±4deg.
Designated use:
The device uses different FMCW transmit signal waveforms for distance and speed measurement. 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:
 Automotive: measure shortest distance to obstacle.
 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.
