Abstract

The radar apparatus may include: a transmission antenna section including a plurality of transmission antennas arranged in a diagonal direction based on a first horizontal interval and a first vertical interval; the receiving antenna part comprises a first receiving antenna group and a second receiving antenna group which are arranged based on a first horizontal interval; a transmission / reception unit that transmits a transmission signal via the transmission antenna unit and receives a reflected signal reflected from a target object via the reception antenna unit; and a processing unit that processes the received reflected signal to derive information of the target object.

Description

technical field [0001] The present invention relates to a radar device comprising a plurality of antennas arranged at horizontal and vertical intervals. Background technique [0002] Generally, a radar device should have a high-resolution angle resolution capability in order to detect or track the distance, speed, and angle of a target device through transmission / reception of radio waves. [0003] For existing radar devices for automobiles, the antenna arrays are arranged side by side with the azimuth axis along the traveling direction of the automobile, so that the angle of the target object located on the road can be predicted. However, when the antenna array is arranged side by side with the azimuth axis, the angle of the object in the elevation direction cannot be detected. [0004] Recently, in order to extract the information of the elevation angle, an antenna pattern is used in which an antenna for the horizontal direction and an antenna for the vertical direction ar...
