Chassis Systems Control Leonberg Model Document Dept. 20 December 2021 FR5CUEC User Manual ITA XC-DA/ESR1 2 Explanation of CW Radar function Continuous-wave radar is a type of radar system where a known stable frequency continuous-wave radio energy is transmitted and then received from any reflecting objects. - Page 4 Model Document Dept. 20 December 2021 FR5CUEC User Manual ITA XC-DA/ESR1 Sawtooth modulation is the most used in FM-CW radars where range is desired for objects that lack rotating parts. Range information is mixed with the Doppler velocity using this technique.

Page 5: Operating Principal Of The Fr5Cuec
The radar sensor’s main task is to detect objects and measure their speed and position relative to the movement of the vehicle in which it is mounted. To do this, the FR5CUEC senses targets by emitting many short frequency modulated waves using the transmit antennas while receiving waves reflected by targets using the receive antennas. -

Chassis Systems Control Leonberg Model Document Dept. 20 December 2021 FR5CUEC User Manual ITA XC-DA/ESR1 4 National Statements 4.1.1 Exposure information (all countries) This device should be installed and operated with minimum distance of 20 cm between the front of device and human body. -
Page 7: User Information
5 User information 5.1 Principle The FR5CUEC radar sensor and control unit (SCU) contains a FMCW radar transceiver operating in the globally harmonized frequency range of 76.0 - 77.0 GHz. It senses targets by emitting many short frequency modulated waves using the transmit antennas while receiving waves reflected by targets using the receive antennas. -
Page 8: Features And Mechanical Design
The FR5CUEC can be concealed in the bumper or fitted in the radiator grill of the vehicle, with minimal impact on the design or cooling air flow. - Page 9 Sensor data fusion The FR5CUEC can utilize sensor data fusion without the need for additional hardware. Sensor data fusion combines the benefits of different sensors and measuring principles in the most effective way possible, providing data that individual sensors working in isolation are unable to generate.

Page 11: Fascia Design Guidelines
Model Document Dept. 20 December 2021 FR5CUEC User Manual ITA XC-DA/ESR1 The radar cone describes the zone where the fascia has to be optimized. Any parts of the vehicle inside the radar cone may influence the radar performance. Cables, brackets, bars etc. should not touch the radar cone. -
Page 12: Installation Hints
FR5CUEC User Manual ITA XC-DA/ESR1 Fascia Classification (FR5CUEC) The two-way radar loss caused by fascia should be as low as possible. High losses decrease the sensor performance regarding range and angle estimation. Therefore it is recommended to achieve a two-way radar loss below 3 dB. - Page 13 Leonberg Model Document Dept. 20 December 2021 FR5CUEC User Manual ITA XC-DA/ESR1 The minimum distance between the sensor radome and the fascia or any other part of the vehicle may not be smaller than 5 mm tbc. This is valid for fascia parts fulfilling the following requirements.
- Page 14 Leonberg Model Document Dept. 20 December 2021 FR5CUEC User Manual ITA XC-DA/ESR1 Multipath reflection Incident RF waves are reflected between components (e.g. the sensor itself, the sensor bracket or an absorber cone) and the sensor cover. The sensor performance can be deteriorated if the reflections hit the sensor.
