  • Publication number: 20200284875
    Abstract: A vehicle radar detection angle adjustment system and angularly adjustable radar thereof are provided. The system comprises a transmission unit, a processing unit, and a receiving unit. The transmission unit generates a radar beam according to an operation frequency. The processing unit, by the adjustment of the operation frequency, changes a dip angle of the transmission of the radar beam from the transmission unit, and generates a feedback signal after receiving the radar beam through the receiving unit. The processing unit is electrically connected with the receiving unit for receiving the feedback signal, so as to compare the beam frequency of the received feedback signal, and select an operation frequency corresponding to the radar beam having the predetermined energy. Therefore, the radar beam is launched at an optimal angle.

  • Publication number: 20200088841
    Abstract: A radar system with angle error determination function and method thereof are provided. The system includes a camera device, a radar device, a calculation module, and an angle calibration module. The camera device captures a surveillance image of a surveillance area. The radar device sends a radar signal toward the surveillance area. The calculation module, according to the surveillance image, acquires an image angle of an object with respect to the vehicle in the surveillance area. Also, the calculation module acquires a radar angle of the object with respect to the vehicle which is produced according to a reflection signal generated when the radar signal meets the object. The angle calibration module, by referring to the image angle, correspondingly calibrates the radar angle. Therefore, the radar angle is immediately calibrated.

    Abstract: A symmetric leaky wave antenna includes a dielectric substrate, an electric wall, and two reflection bore arrays. The dielectric substrate has a first and a second metal layers disposed on two opposite faces thereof. The first metal layer has a feed end and two travelling wave sides. The electric wall is disposed between two travelling wave sides, with the two travelling wave sides symmetrically disposed with respect to the electric wall. The two reflection bore arrays are symmetrically disposed along the two travelling wave sides, respectively, with the electric wall arranged at a central line between the two reflection bore arrays. The two reflection bore arrays pass through the first metal layer, the second metal layer, and the dielectric substrate. The reflection bore array and the electric wall reduce the leakage rate of the electromagnetic wave, thus increasing the gain value of the antenna.

    Abstract: A school bus radar system includes a main unit mounted in the school bus, and two radars protrudingly arranged on the bus body of the school bus in a tilted manner and respectively electrically connected to the main unit. When the main unit is switched to a monitoring mode, the main unit generates a radar activation signal to activate the radars in generating a signal, making the signals generated by the monitoring sources of the radars form an intersection network. The monitoring source of each radar defines a normal line. Accordingly, the intersection type three-dimensional spatial monitoring network of the radar system of the present invention is proposed for individual warnings to facilitate the driver making good judgments or stopping the running school bus in an emergency.
