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.
