Description
Technical field
The present invention relates to millimetre-wave radar technical field more particularly to a kind of millimeter-wave automotive anti-collision radar systems.
Background technology
With the development of economy, vehicle population continues to increase, and causes urban traffic blocking, traffic accident takes place frequently, right
Traffic accident analysis shows that, 80% or more traffic accident is caused by due to driver's reflection not in time, is more than 65% vehicle phase
It hits and belongs to rear-end collision, and in rear-end collision, 45% is since driver does not see the vehicle in front clearly, and 30% is to find there is danger
Danger is too late when taking measures.Therefore it needs to provide and can the pre- of timely early warning be made to the case where direction of traffic front in time
Alert system is prejudged with assist driver.
Invention content
Technical problem to be solved by the present invention lies in provide a kind of millimeter-wave automotive that can judge vehicle front situation
Anti-collision radar system.
The present invention is to solve above-mentioned technical problem by the following technical programs：
A kind of millimeter-wave automotive anti-collision radar system, including oscillator, transmitting antenna, reception antenna, frequency mixer, processing
Device, controller and outlet terminal；Oscillator concussion generates millimeter wave and launches by transmitting antenna, and the reception antenna receives
By the millimeter-wave signal that vehicle front object reflects, and by being transported to processor, processor pair after frequency mixer screening amplification
Millimeter-wave signal is handled to obtain the speed, orientation, range information of objects in front, and is carried out pair with the operating status of this vehicle
Than analysis, it to judge whether to need to change driving states, and will determine that result is transferred to controller, transmitted result by controller
To outlet terminal to prompt driver to make a response.
Preferably, the outlet terminal includes display and vehicle audio.
Preferably, the transmitting antenna and reception antenna are connect with the same circulator.
A kind of the advantages of millimeter-wave automotive anti-collision radar provided by the invention, is：It is timely found by millimetre-wave radar
Front situation reminds driver to make a response in advance, reduces contingency occurrence probability, improves traffic safety.
Description of the drawings
Fig. 1 is a kind of schematic diagram for millimeter-wave automotive anti-collision radar system that the embodiment of the present invention is provided.
Specific implementation mode
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, and reference

On, the oscillator concussion generates millimeter wave and enters circulator and emitted by transmitting antenna 1, and reception antenna 2 is received by front
Millimeter wave that object emission is returned simultaneously is amplified into processor by frequency mixer screening, processor to millimeter-wave signal at
Reason is compared and analyzed with obtaining the speed, orientation, range information of objects in front with the operating status of this vehicle, to judge to be
No to need to change driving states, specific works circuit and data processing algorithm are algorithm commonly used in the art, and details are not described herein again；
Processor will determine that result is transferred to controller, and assist driver to front road by controller is transferred to outlet terminal
Condition is prejudged, and to reduce the probability that traffic accident occurs as possible, the outlet terminal includes display screen and vehicle audio, with
Just driver promptly and accurately receive traffic information.
Since millimetre-wave radar has stable detection performance, it is not easy to be influenced by testee surface shape, color etc.,
It is not influenced by weather conditions, can be with all weather operations, the features such as detection range is remote, reliable for operation, and millimetre-wave radar size
It can accomplish to minimize, be suitble to install on automobile, therefore there is good promotion prospect in automobile warning aspect.
Particular embodiments described above has carried out further in detail the purpose of the present invention, technical solution and advantageous effect
It describes in detail bright, it should be understood that the above is only a specific embodiment of the present invention, is not intended to restrict the invention, not
It is any modification that those of ordinary skill in the art make the present invention, equivalent under the premise of being detached from the spirit and principles in the present invention
Replace, improve etc., it should all fall within the protection domain of claims of the present invention determination.
