Abstract
The utility model discloses an automotive radar system which is characterized in that the radar system includes a transmitting antenna for transmitting electromagnetic waves, four receiving antennas for receiving reflected electromagnetic waves of an object, an antenna panel which is provided with the transmitting antenna and the receiving antennas, an antenna drive disk which is respectively connected with the transmitting antenna and the receiving antennas, and an information processing device which is connected with an output bus of the antenna drive disk. By the adoption of the automotive radar system, the object can be accurately detected within a wide range, and the track of a high-speed object can also be captured.
Description
Technical field
The utility model relates to a kind of radar system, particularly a kind of vehicle radar system.
Background technology
Existing vehicle radar system mostly is single pulse mode, its doing well on azimuthal resolution, and can be with small-sized realization the relatively, but if to enlarging investigative range, just needs increase the wave beam amplitude of antenna, yet, this will cause detectable range narrow, and problem such as azimuthal resolution deterioration.
The utility model content
The utility model purpose is: propose a kind of vehicle radar system, it can be surveyed things in a wideer relatively scope, and can carry out information processing at a high speed.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of vehicle radar system, described radar system comprises:
Be used for the electromagnetic transmitting antenna of emission;
4 receiving antennas that are used for the reflection electromagnetic wave of reception object;
Antenna plate disposes described transmitting antenna and described receiving antenna on the described antenna plate;
The antenna driving-disc, described antenna driving-disc is connected with described transmitting antenna and described receiving antenna respectively; And
Signal conditioning package, described signal conditioning package is connected with the output bus of described antenna driving-disc.
As preferred version, described 4 receiving antennas are separately positioned on 4 angles of automobile.
As preferred version, described transmitting antenna is arranged on the rectangular centre that is surrounded by 4 receiving antennas.
As preferred version, described radar system also is provided with an error correction receiving antenna, and described error correction receiving antenna and described transmitting antenna are arranged on same position.
As preferred version, described information processing apparatus is set to a vehicle-mounted computer main frame.
The beneficial effects of the utility model are: adopt the utility model to survey accurately object in wideer scope, but also can catch the track of high speed object.
Description of drawings
Fig. 1 is the utility model fundamental diagram;
Fig. 2 is the utility model system architecture diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1: a kind of vehicle radar system, described radar system comprises: transmitting antenna 1, receiving antenna 2-5, error correction receiving antenna 6 and an antenna driving-disc 9, described receiving antenna 2-5 is distributed in four corners of automobile respectively, and all be connected to described antenna driving-disc 9, described, described transmitting antenna 1 is arranged at the automobile middle part with described error correction receiving antenna 6, and all is connected to described antenna driving-disc 9.Again in conjunction with Fig. 2 as can be known, described antenna driving-disc 9 is connected to signal conditioning package.
During work, transmitting antenna 1 sends electromagnetic wave, during first barrier 7 before running into car, electromagnetic wave is received by receiving antenna 4 and 5 respectively through the reflection of first barrier 7 again, receiving antenna 4 and 5 is sent to signal antenna driving-disc 9 respectively, and antenna driving-disc 9 is delivered to signal conditioning package by bus with signal and handled, after handling by analysis, can draw the spacing of first barrier 7 and automobile, and first barrier 7 is with respect to the speed of automobile.In this process, error correction receiving antenna 6 also receives electromagnetic wave simultaneously as the reference contrast, thereby reduces error.
During second barrier 8 after electromagnetic wave runs into car, through its reflection, received by receiving antenna 2 and 3, pass through processing procedure same as described above then, draw second barrier 8 with respect to speed and the spacing of automobile.
More than show principal character and the innovative point of only having described this programme.Those skilled in the art should understand, and this programme is not restricted to the described embodiments.Under the prerequisite that does not break away from the innovation point and protection domain, this programme also has various variations, and these changes and improvements all will fall in the claimed scope of this programme.The claimed scope of this programme is limited by appending claims and equivalent thereof.
