4General 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.
The UMRR sensor consists of two printed circuit boards: The DSP board and the RF
transceiver board.
The major component of the DSP board is the DSP TMS320F28335 which integrates flash
memory (for program code) and RAM. The DSP provides interfaces to external RAM,
EEPROM, CAN bus and RS485 (both for data communication). The DSP controls the RF
transceiver board via an SPI interface.
The RF transceiver board consists of transmit and receive antennae and the RF circuitry that
includes the radar MMIC SC3001.2. The radar MMIC generates the transmit signal and down
converts the receive signals into baseband. The analog baseband signals are then routed to
the DSP board and digitized by the DSP’s built-in ADC. The digital data are further processed
on the DSP.
The MMIC also features a PLL circuitry to calibrate and linearize the transmit frequency
ramps, a DAC for setting the VCO voltage (corresponding to the transmit frequency) and an
SPI interface for receiving the control signals from the DSP.
For the time of emission the device is one fixed point to point application.

4.2 Transmit Signal
The UMRR transmit frequency is located in the 24 GHz ISM band (24050 MHz to 24250 MHz),
the used bandwidth is smaller than 200 MHz. The maximum transmit power is 12.7dBm.
Antenna type 31 is used, consisting of one transmit and two receive antennas, both linear
polarized. The 2 way 3 dB cut-off angle in azimuth ±28deg. and in elevation ±5deg.
The device uses different FMCW transmit signal waveforms for distance and speed
measurement.
4.3 General Performance Data
As soon as the device is powered up, the unit (TX and RX) starts operation.
