smart microwave sensors GmbH 1 Intended usage / application The UMRR-09xx (UMRR) device is used as a field disturbance sensor. The user installs the UMRR on a stationary or moving platform. As soon as power is applied to the UMRR, transmit and receive start operating. The UMRR sensor permanently monitors the volume within the vicinity of the antenna field pattern (compare section 5). The sensor itself is not rotated and has no moving parts. The sensor acts in measurement cycles of 30 .. 150ms.
smart microwave sensors GmbH 2 Detection Performance Data 2.1 FMCW Narrowband Mode Parameter Value Basics: Frequency Band 24.000 GHz to 24.250 GHz Bandwidth < 100 MHz Transmit Peak Power (Individual Sensor) <= 20dBm Antenna: Antenna Type Type 29 Angle Interval (field of View) Type 29: +-20 degree Detection Performance: Range Interval Minimum Range: 0.

smart microwave sensors GmbH 3 Radar System Components 3.1 Individual sensors The main task of the sensor component is the detection of any obstacles in the field of view. Range, relative radial speed and angle of each object are measured. Its interface to the central processor is the object list reported cycle by cycle. Figure 1: Photograph of the UMRR Sensor Each sensor comprises a CAN port for communication and an SPI port for data logging. 3.1.
smart microwave sensors GmbH 3.1.2 Sensor Software Identification The sensor software is given as follows: Example: Umrrflsh_ID0_RF1208_DSP0436_Rel005_2004-02-18_P_ACCSG_OUV Umrrflsh Software for Flash or RAM Download ID0 Sensor ID in the network RF1108 RF Module Serial Number DSP0366 DSP Module Serial Number Rel005 Software Release P Platform Software ACCSG Parameter Settings for ACC Stop&Go Application OUV Software for Upside Down Mounted Sensor 3.1.
smart microwave sensors GmbH The UMRR consists of a DSP (digital signal processing) board controlling the RF circuit. All interactions with the user are through the DSP board interfaces, mainly CAN (Controller Area Network) interface. The DSP board controls the VCO through an internal SPI (Serial Peripheral Interface). The VCO signal is split into transmit and receive path. The transmit path feeds the TX antenna. The receive path feeds mixers for the receive antennas.

smart microwave sensors GmbH Figure 11: 3D representation of Housing V5.7 7.3 Coverage of the sensor The sensors have a weather proof plastic radome, which is optimized along with the antenna. It is not necessary to protect the sensors by any additional means. Hence, for an optimum detection performance, do not mount the radar behind bumper material or similar covers. The effective range will then be reduced depending on the transmission attenuation of the material.
smart microwave sensors GmbH 8 Co-ordinate System Figure illustrates the co-ordinate system of a radar system . - the data are reported in Cartesian co-ordinates. If sensors are used stand-alone, without the central ecu, they report the targets in a sensor co-ordinate system which is specified similar to the picture given below. - The sensor position respresents the origing then - The sensor pointing direction is equal to the x-axis - The data are reported in polar co-ordinates.
