Put, to guarantee the correct installation of radar, improve the safety driven.
This utility model be employed technical scheme comprise that for achieving the above object：A kind of vehicle blind zone Radar Calibration device,
It includes fixed support and power supply adaptor, and Doppler signal simulator is fixed on fixed support using fixed cover and handle by it
On, described Doppler signal simulator adopts setting electrical box and support on connecting plate, and described support is located at just going up of electrical box
Side, support is provided with universal level gauge, is provided with axial-flow fan between the upper bracket in described electrical box and undersetting, and passes through
The electrical box front that the position of flow fan maximum reflection area is corresponding is provided with calibration line.Described axial-flow fan is provided with 22 fans
Leaf.
A kind of scaling method of vehicle blind zone Radar Calibration device, comprises the following steps：
1）Setting calibration position
Caliberating device is placed on the fixed point after automobile to be calibrated, described fixed point is sent out for car radar to be calibrated
The point of maximum intensity that ejected wave and echo are overlapped；Concrete operations are to utilize plumb line, make by Doppler signal simulator
The plummet of calibration line is overlapped with the fixed point on ground, is then adjusted to and radar altitude Doppler simulation simulator centre-height
Unanimously, then by universal level gauge caliberating device is adjusted to level；
2）Radar Calibration
The blind area radar of activation automobile, radar emission goes out the microwave of 24GHz, after microwave is calibrated device reflection, formation
Echo is superimposed with transmitted wave, then is received by radar, thus simulating the Doppler signal of a movement；Because caliberating device is put
It is placed on fixed point, by comparing the position of radar received wave, you can the setting angle determining radar is the need of adjustment.
Beneficial effects of the present invention are：Doppler signal simulator is arranged on fixation by fixed cover and handle by this device
On support；Doppler signal simulator includes electrical box and universal level gauge, and everything level gauge is arranged on the surface of electrical box；
It is provided with axial-flow fan, it is provided with 22 flabellums, drives through-flow by direct current generator between upper bracket in electrical box and undersetting
Fan high-speed rotation, the flabellum using rotation reflects to radar transmitting wave, and so that echo is overlapped with transmitted wave, from
And simulate Doppler signal.And then the setting angle of demarcation blind area radar, improve its detection accuracy, to ensure traffic safety.
The fixed support of this device is made up of aluminium section bar, is easily installed and dismantles, and can be directed to the radar altitude of different automobile types to mould simultaneously
Intend device to be highly adjusted.
