1. General product description
The present technical customer documentation describes CR5CPCCF, 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 CR5CP 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.
Using the Bosch chirp sequence radar modulation, the CR5CP 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.

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
CR5Plus radar sensors. If these requirements are not met, the sensor performance can be
degraded.
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

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 (CR5CP):
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:
±80° (1) (tbc) in horizontal direction (not including misalignment)
±20° (tbc) in vertical direction (not including misalignment)
(1) Valid for angle measurement range of ±70°

2.1.1.2. Fascia design guidelines
Material
Material with low dielectric constant (r) and low dielectric loss factor tanδat 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 tanδof the painted plate used as fascia.
Fascia Classification (CR5CP)
The two-way radar loss caused by the fascia should be as low as possilbe. High losses decrease
the sensor performance regarding range and angle estimation. Therefore it is recommended to
achieve a two-way radar loss below 4 dB(t.b.c.). This corresponds to a loss of 20% of sensor
range.

within a tolerance ±0.02. Dielectric loss factor tanδ shall be <0.03.
2. 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 tanδ shall be <0.05. This is the case for painted
bumper especially when various colors are used.
3. Reflection coefficient >-6 dB
is achieved when fascia has no optimized thickness or a painting with high metallic content is used.
The attenuation may exceed the maximum allowed limit.
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 µm (corresponding
to ISO 1302 class N10; VDI 3400 class 45).

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.
Maximum angle between radar cone and fascia
The angle αbetween the radar beam inside the radar cone and the fascia may not be larger than
80° anywhere inside the radar cone
Figure: Maximum angle between fascia and radar cone
Minimum distance between sensor and fascia
The minimum distance between the sensor radome and the fascia or any other part of the vehicle
may not be smaller than 5 mm.
This is valid for fascia parts fulfilling the following requirements.
Figure: Minimum distance above sensor radome
Vertical tilt of fascia (CR5CP)
The vertical tilt angle between the sensor normal and the surface normal of the fascia shall be in
the range according to the following table.

Curvature of fascia for CR5CP
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).
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.
