Description
Technical field
The utility model belongs to radar communication, automotive electronic technology and Wide band array antenna field, and in particular to for one
Kind vehicle-carried microwave Sidelobe radar array antenna.
Background technology
With the development of auto industry, either producer or consumer starts increasingly heavier to ride safety of automobile problem
Depending on.In statistics of traffic accidents, about 85% rear-end collision collision is shone because of the negligence of driver.Therefore,
How to control or avoid car crass to become research hotspot, automobile collision avoidance radar technology receives the attention of more and more people,
Having become an important technology for weighing vehicle safety performance.With ultrasonic wave, infrared ray, laser system automobile collision preventing
Radar is compared, millimeter-wave automotive anti-collision radar has with roomy, high resolution, part dimension is small, light weight, it is small, can fit
The features such as answering atrocious weather environment and all weather operations, while the distance of target can be not only detected, it can also measure
The relative velocity of target and azimuth have well adapting to property and stability.
Detection Techniques and the quality of beam-forming technology directly affect precision and the accuracy of automobile collision avoidance radar, in recent years
Carry out automobile collision avoidance radar technology and obtain rapidly to develop, development trend includes following several:First, using ultrasonic wave, laser etc.
Simple beam Detection Techniques, while realize that vehicle front multi-angle detects using more set sensors and signal handling equipment, such as
Chinese patent Multi probe antenna reversing automobile backsight Anticollision Radar (patent No. 97237819.7), a kind of alarm of automobile collision avoidance radar
Device (patent No. 200620004241.4), a kind of method and device of processing alarm information for anti-collision laser radar system of vehicle
(patent No. 201010229331.4), but cannot largely be used due to ultrasonic wave and laser are affected by weather conditions, simultaneously
More set sensor detection costs greatly increase；Second, it is detected using microwave, millimeter wave simple beam, wave beam is narrow, high resolution is it
Advantage, such as Chinese patent millimeter-wave automotive anti-collision radar device (patent No. 01211040.X), all-digital intelligent type automobile are prevented
Radar (patent No. 200820213509.4) is hit, but because simply simple beam detects, greatly limits the spy of automobile collision avoidance radar
Scope is surveyed, the method made up is to be placed on different angle using more set radar-probing systems to be carried out at the same time detection, eventually because of cost
It greatly increases and scheme is made to become infeasible；3rd, the scanning of multi-beam, ripple are realized using microwave, millimeter-wave frequency phased array
Beam is because being differently directed for frequency changes, such as the microwave automobile bump-proof driving radar device (patent No.
, but the relatively narrow investigative range for being its inadequate natural endowment, directly limiting beam scanning of working band 200320120396.0).
In conclusion at present automobile collision avoidance radar technology generally existing it is affected by environment it is big, of high cost, investigative range is narrow,
The defects of stability is poor, it is impossible to ensure security of the automobile during sailing.Especially because in array antenna system design
Shortcoming, has seriously affected the working range, dynamic range and sensitivity of vehicle-carried microwave radar.
