CC-DA/ESR1 FR5CPCCF 08 Aug 2019 1. General product description The present technical customer documentation describes FR5CPCCF, for which the Robert Bosch GmbH has the assigned responsibility. In addition, it contains noncommittal descriptions of components and functionalities, which are not in the responsibility of Robert Bosch GmbH, but nonetheless determine or influence the behavior and performance of the particular vehicle type series. 1.1. Main functions and properties of the product 1.1.1. Principle The FR5CP 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. Distance and relative speed are determined via beat frequency (due to travelling time of the waves) and phase differences between ramps (due to change of distance in short time). By using the antenna diagram the angles of departure and arrival of the radar waves can be determined. the Bosch chirp sequence radar modulation, Using the FR5CP allows unambiguous determination of relative speed in a single measurement cycle. Therefore, no complex object models are needed for ambiguity resolution. The radar reflections (strength, distance and relative speed, angular direction, and derived values) are basis for building a comprehensive model of the sensed environment. Page:

CC-DA/ESR1 FR5CPCCF 08 Aug 2019 2. System description 2.1. Vehicle integration interfaces This chapter describes the requirements for all parts mounted in front or around the sensor, like painted bumper, unpainted cover and emblem/radome, regarding RF integration at 77 GHz with FR5plus radar sensors. Values are marked with t.b.c. or t.b.d. showing that they have to be confirmed or defined during the development process. As product development is an on-going process, we reserve the right to make amendments in line with technical progress. The radar sensor performance should be influenced as low as possible by the installation behind a fascia. Therefore the two-way radar loss by the fascia should be as low as possible and the reflection attenuation must fulfill the requirements listed below. Vertical misalignment will cause additional attenuation reducing the maximum range. Horizontal misalignment will cause reduced detection at higher azimuth angles. Ghost target detection caused by interference signals of multiple reflection at fascia and metallic parts of the vehicle must be avoided. A simulation can be offered to evaluate the risk and the need of using absorber material to suppress this unwanted signal. Because the threshold of detection is very low, a high attenuation is required. Plastic material can only achieve high enough attenuation, if carbon black is added. 2.1.1.1. Radar Cone Radar Cone for PLUS Family 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. The fascia in this zone may not have bends and edges as well as changes in thickness or material or painting. Based on the footprint on the top side of the radar PCB the cone is characterized by a vertical and a horizontal opening angle. The footprint is centered regarding to the sensor housing. A CAD model of the radar cone is available. The footprint for radar cone has the following dimensions: (W x H) 55 mm x 55 mm Page:

CC-DA/ESR1 FR5CPCCF 08 Aug 2019 Figure: Footprint of the radar cone. For better visibility the footprint is shown on top of the sensor housing. Radar cone definition for covered installation (FR5CP):
The horizontal opening angle depends on the angle range that is evaluated by the sensor in azimuth and elevation, whereby the opening angle of the radar cone has to be larger than the angle range that is evaluated. For covered integration the radar cone is 10 larger than the used angle range that is evaluated by the sensor. Radar cone:
70 (1) in horizontal direction (not including misalignment) 20 in vertical direction (not including misalignment)

CC-DA/ESR1 FR5CPCCF 08 Aug 2019 2.1.1.2. Material Fascia design guidelines Material with low dielectric constant (r) and low dielectric loss factor tan at 77 GHz should be used. Recommended are materials based on polypropylene (PP) and polymethyl methacrylate
(PMMA), while materials like polycarbonate (PC) and acrylonitrile butadiene styrene (ABS) are still ok. The material shall be homogenous, compounds including glass fiber, carbon fiber or metal particles are not recommended. The fascia shall be designed for radar transparency. The thickness shall be a multiple of the half wavelength (in the material) to minimize the influence of the fascia. The quality criteria of radar transparency is the reflection coefficient of the radome/fascia. Tolerances of the overall thickness and the dielectric constant of the used material influence the amount of reflection at the radome/fascia. Additional influence occurs due to curvature of the fascia. Therefore the radius has to be as large as possible. With sharp edges the negative influence will increase significantly. Not allowed are ribs, structures and steps changing the thickness of the radome/fascia. Painting The layer structure of the painting, typically made of three painting layers consisting of primer, base coating and clear coating, will increase the effective permittivity value r,eff and dielectric loss factor tan of the painted plate used as fascia. Fascia Classification (FR5CP) 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:

CC-DA/ESR1 FR5CPCCF 08 Aug 2019 Classification of reflection caused by the fascia The examples described in the classification of reflection are derived from evaluation of flat plates with constant thickness and homogeneous material. Deviations from this situation may cause a change in classification and the vertical tilt angle of fascia has to be increased. Surface Properties of the fascia The surfaces of the fascia shall not exceed an average roughness height of 20 m
(corresponding to ISO 1302 class N10; VDI 3400 class 45). Page:

The valid issue of this template is filed in CC-DA process landscape. 1. Reflection coefficient <-15 dB is achieved when fascia has optimized thickness within a tolerance of 0.1 mm and permittivity within a tolerance of 0.02. Dielectric loss factor tan shall be <0.01. With such low reflection a vertical tilt angle of 0 is possible. This is the case for unpainted or a single e.g. black paint cover. Also well designed emblems without air gap inside may be usable. 2. Reflection coefficient <-10 dB is achieved when fascia has optimized thickness within a tolerance of 0.2 mm and permittivity within a tolerance 0.02. Dielectric loss factor tan shall be <0.03. With such reflection a vertical tilt angle of 0 must be avoided. 3. Reflection coefficient <-6 dB is achieved when fascia has optimized thickness within a tolerance of 0.2 mm and permittivity within a tolerance of 0.2. Dielectric loss factor tan shall be <0.05. With such reflection a vertical tilt angle of >18 is required. This is the case for painted bumper especially when various colors are used. 4. Reflection coefficient >-6 dB is achieved when fascia has no optimized thickness or a painting with high metallic content is used. The attenuation will exceed the maximum allowed limit.

CC-DA/ESR1 FR5CPCCF 08 Aug 2019 2.1.1.3. Installation Hints To enable the full performance of the radar sensor, it is recommended to use the following installation hints and guidelines for the RF integration of the sensor. Sensor rotation around radome normal (FR5CP) The sensor shall not be rotated more than 1.5 around the normal of the radome surface. Maximum angle between radar cone and fascia The angle between the radar beam inside the radar cone and the fascia may not be larger than 70 anywhere inside the radar cone.

CC-DA/ESR1 FR5CPCCF 08 Aug 2019 Table: minimum vertical tilt angle of fascia to sensor normal Curvature of fascia for FR5CP Curvature of the fascia may influence the radar performance, especially with low vertical tilt angles. The minimum radius of the curvature shall be according to the following rules:
R > 350 mm, no significant influence expected R < 350 mm, significant influence possible, has to be evaluated R < 200 mm, significant influence expected, not recommended Absorber around the sensor It is highly recommended to use a cone made of absorber material around the radar cone of the sensor to prevent ghost targets. The design of the absorber cone must fulfill the following design guidelines (reflection from outside the radar cone, multipath reflection). Reflection from outside the radar cone Reflections from structures located outside the radar cone have to be avoided. Furthermore interference signals picked up by the sensor antennas should be avoided by keeping a minimum distance (d) of 5 mm to 10 mm for parts in front of the sensor. Even with compliance to the radar cone, reflections at parts outside the radar cone may disturb the received signal. Reflections at parts causing an interference signal to the receiving antenna and reflections at parts getting to the receiving antenna after a second reflection at the fascia
(multipath reflection). Page:

CC-DA/ESR1 FR5CPCCF 08 Aug 2019 Closed surfaces of brackets and masks made of metal or high reflecting material need a tilt angle being arranged that the reflection is not received by the receiving antennas of the sensor. Figure: Reflection at bracket or mask For closed surfaces (masks) in azimuth, the angle between mask surface and the normal vector n of the sensor shall be above 75 for parts outside of the radar cone. For closed surfaces (masks) in elevation, the angle between mask surface and the normal vector n of the sensor shall be above 20 for parts outside of the radar cone. Reflections of incoming signals at bracket or shielding absorber are coming back to the sensor if reflection at the bumper occurs. The figure below shows the situation which should be avoided. The worst case happens if the combination of the vertical tilt angles of shielding and bumper is 1 = 2 / 2 . For a low interference signal the condition shall be:
