It encloses, but is merely representative of the selected embodiment of the utility model.Based on the embodiments of the present invention, those skilled in the art exist
Every other embodiment obtained under the premise of creative work is not made, is fallen within the protection scope of the utility model.
When millimeter-wave automotive radar specific works, vehicle response echo caused by millimetre-wave radar of different model is
It is distinguishing, and the same position of same automobile be also for the echo of different angle incidence wave it is different, be unfavorable for
Millimeter-wave automotive radar is detected and is identified to automobile.In view of the above-mentioned problems, the utility model provides a kind of automobile thunder
Up to echo enhancement device, echo enhancement device is arranged by the specific position in automobile, radar return can be enhanced, to be conducive to
Millimeter-wave automotive radar carries out target identification.It is described in detail below by specific embodiment.
The utility model embodiment provides a kind of automobile radar return enhancement device, including corner reflector；
The corner reflector includes two or three reflectings surface interconnected, between reflecting surface described in any two
It is mutually perpendicular to；
The corner reflector is arranged on automobile.
The specific working principle is as follows for the corner reflector: the radar incidence wave of a direction is incident on its of corner reflector
In on a reflecting surface, which is reflected into the radar incidence wave of described a direction on another reflecting surface, and so on,
Radar incidence wave reflects back after multiple reflections along original direction.
In order to achieve the purpose that enhance radar return, each reflecting surface is plane, and the reflecting surface can be to appoint
It anticipates shape, the shape of reflecting surface described in any two can be same or different；
The reflecting surface all can be any one shape in triangle or rectangle or sector, i.e., the described corner reflector can
Think any one in triangle corner reflector or rectangle corner reflector or fan-shaped corner reflector, in order to enhance echo ability,
The corner reflector can be isosceles right triangle corner reflector 101 or square corner reflector 201 or 90 ° of fan-shaped corner reflections
Any one in body 301, as shown in Figs. 1-3.
Preferably, the reflecting surface is square reflecting surface 202 or 90 ° of fan-shaped reflectings surface 302.
The radar cross section area of the reflecting surface is bigger, that is, the echo area of the corner reflector is got over
Greatly, the echo ability of the corner reflector is stronger.For isosceles right triangle corner reflector 101 or square corner reflector
201 or 90 ° of fan-shaped corner reflectors 301, when the intersection length of the reflecting surface is identical, the radar mesh of square reflecting surface 202
Effective cross-sectional area maximum is marked, the radar cross section area of 90 ° of fan-shaped reflectings surface 302 takes second place, isosceles right triangle
The radar cross section area of reflecting surface 102 is minimum, i.e. the echo ability of square corner reflector 201 is most strong, 90 ° of sectors
The echo ability of corner reflector 301 is taken second place, and the echo ability of isosceles right triangle corner reflector 101 is most weak.Specifically, just
The maximum value formula of the radar cross section area of rectangular reflecting surface 202 is90 ° of fan-shaped reflectings surface 302
The maximum value formula of radar cross section area beIsosceles right triangle reflecting surface 102
The maximum value formula of radar cross section area isWherein, σ is that the radar target of reflecting surface has
Area of section is imitated, λ is the wavelength of radar incidence wave, and L is the intersection length of two neighboring reflecting surface.
The corner reflector includes three and is connected with each other and any two mutually vertical reflecting surface.
Herein, for unidirectional incidence wave, the number of the reflecting surface is more, the echo energy of the corner reflector
Power is stronger.E.g., including there are three the echo abilities of the corner reflector of reflecting surface than including the corner reflection there are two reflecting surface
The echo ability of body is strong.
In addition, the corner reflector material is that metal or the corner reflector surface are coated with metal layer；
Preferably, the corner reflector material is copper, and/or, the corner reflector surface is coated with copper.
Metallic conduction ability is stronger, and echo ability is stronger, and the conductive capability of copper is very strong, therefore the corner reflector of copper material
And surface be coated with copper corner reflector echo it is very capable, vehicle is detected and is identified conducive to radar.
The corner reflector is independently arranged on specified automobile parts or is taken shape on specified automobile parts.
Preferably, the collision prevention girders 601 of automobile, vehicle shell 701, wheel hub, plastic decorative cover, glass are arranged in the corner reflector
Cover, lampshade, on logo or automotive interior.
Above-mentioned automobile parts include the peculiar information of vehicle, and the above-mentioned position of automobile, radar is arranged in the corner reflector
By receiving the echo of above-mentioned position, it can recognize that the peculiar information of vehicle, be conducive to radar and carry out target identification.
Since the incident angle of radar incidence wave is different, multiple corner reflectors can be set on automobile, and
The radar reflection direction of the different corner reflectors is different.
Herein, projected area of the corner reflector in the plane vertical with radar incidence wave is bigger, and the angle is anti-
The echo ability of beam is stronger.
For example, for including the corner reflector there are two the reflecting surface, when radar incidence wave is described anti-perpendicular to two
When penetrating the intersection in face, projected area of the corner reflector in the plane vertical with radar incidence wave is maximum, the corner reflection
The radar return ability of body is most strong.
Herein, the corner reflector is independently arranged on specified automobile parts by fixed device.
