Problems solved by technology

This leads to inhomogeneity of the wave passing through the radome and thus to impaired performance of the wave emitting member
Even though attenuation and reflections across the signal are still weak, this non-uniformity complicates the detection of obstacles, making the signal difficult to exploit

Embodiment Construction

[0031] now refer to figure 1 , which shows a body panel 2 , here a front bumper, comprising a protection device configured to protect at least one component for emitting waves.

[0032] This protective device, also called radome 4 , protects wave emitting members (not shown) on the front surface of the motor vehicle located behind radome 4 . In the following, an example is described of a radar placed behind the radome 4 at the front of the vehicle. Those skilled in the art will appreciate that, depending on the function of the radar, the radar may be mounted at another location on the vehicle, such as at the rear, on the side or on the roof. The number of wave emitting members may also vary.

[0033] The radome 4 is designed to be at least partially penetrated by the waves emitted by the wave-emitting means.

[0034] It must therefore be at least partially transparent to these waves, at least at the wave-transparent regions. As previously stated, "transparent to waves emit...

Abstract

The invention relates to a radome (4) for a motor vehicle, comprising a main body (8) comprising at least one zone transparent to the waves emitted by the wave-emitting element and intended to be traversed by said waves, the zone comprising a face (14) comprising an alternation of first parts (10) covered by at least one layer of paint and second parts (12) not covered by the layer of paint, the first and second parts (10, 12) forming at least one decorative pattern (6) and being arranged in such a way as to make the decorative pattern (6) transparent to the waves emitted by the wave-emitting element.

Description

technical field [0001] The present invention relates to motor vehicles equipped with wave-emitting components, and more particularly to protection devices designed to protect the wave-emitting components of these motor vehicles. Background technique [0002] More and more motor vehicles have body parts fitted with wave-emitting components, for example one or more radars of the ACC type (acronym for the English term "Adaptive Cruise Control") which emit radio waves. [0003] Such wave-emitting members are often shielded and protected from, for example, adverse weather by protective devices known as "radomes". In the following description, the term "radome" is used as a synonym for "protective device". [0004] These radomes are intended to pass through the waves emitted by one or more emitting members, so they must be transparent to these waves. "Transparent to waves emitted by a wave emitting member" refers to the ability of a material to be traversed by an incident wave f...
