Abstract

The embodiment of the invention discloses an antenna array and a radar. The antenna array comprises a receiving antenna array and a transmitting antenna array; the receiving antenna array comprises a plurality of receiving antenna units which are arranged at intervals along a first direction, and each receiving antenna unit comprises a plurality of receiving antennas which are arranged at intervals along a second direction; the transmitting antenna array comprises a plurality of transmitting antennas which are arranged at intervals along a first direction and a second direction; one of the first direction and the second direction is a horizontal direction, and the other one is a vertical direction. According to the embodiment of the invention, the plurality of receiving antenna units and the plurality of transmitting antennas are arranged in the antenna array, and the number of the receiving antennas and the number of the transmitting antennas in the vertical direction of the antenna array are increased, so that the angle resolution of height measurement of the antenna array is smaller, the precision of height measurement of the antenna array is improved, and the antenna array is more convenient to use. The technical problem that a radar in the prior art is poor in precision during height measurement is solved.

Description

technical field [0001] The embodiments of the present application relate to the field of radar, and in particular, to an antenna array and a radar. Background technique [0002] 4D imaging radar technology refers to a technology that uses a large radio frequency channel array to detect the relative speed, distance and orientation of objects on the road, as well as the height of objects above the road. Existing 4D imaging radars generally use an antenna array composed of a single-row receiving antenna and multiple-column transmitting antennas, so as to measure the angle in the horizontal direction and the vertical height. When performing altimetry based on the existing 4D imaging radar, due to the limitation of the antenna array structure, the angular resolution of the measurement is relatively large. However, the larger the angular resolution is, the worse the measurement accuracy is. Therefore, the existing 4D imaging radar has poor altimetry accuracy and is difficult to m...
