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 in the band from 77 GHz to 81 GHz, the used bandwidth is
smaller than 4 GHz. The maximum transmit power is 31 dBm.
The device uses different FMCW transmit signal waveforms for distance and speed
measurement.
4.3 General Performance Data
After power on or reset, the sensor readings are within specified performance within <2
seconds. In Table 4-1 the general performance data of UMRR-96 Type 153 are given.
