Title:
水平方向にデジタルビーム形成を行ないオフセットされた送信器の位相を比較することにより垂直方向の物体測定を行なう撮像レーダセンサ
Document Type and Number:
Japanese Patent JP6920198
Kind Code:
B2
Abstract:
According to the invention, a device and a method are provided for determining the position of an object, in particular a moving object, in the three-dimensional space. The device comprises at least two switchable transmitting antennas having a different vertical position of the phase center as well as a plurality of receiving antennas which are arranged in series. The transmitting antennas are arranged in the horizontal direction and at a distance that corresponds to the distance of the receiving antennas. The transmitting antennas are vertically offset with respect to each other by a value that is less than or equal to half the free-space wavelength of the transmitted signal. The transmitting antennas can otherwise be arranged at any position around the receiving antenna. Horizontal beam sweep across a wide angular range is carried out according to the method of “digital beamforming”. The measurement of the vertical object position is carried out by phase measurement between the antenna beams when the transmitting antennas are sequentially switched.
