The invention discloses an array antenna arrangement and an automobile corner radar, wherein the array antenna arrangement includes m transmitting antennas arranged in a transverse direction and n receiving antennas arranged in a transverse direction: The distance between centers is d, where m is an integer greater than 2, n is an integer greater than 1, and d is greater than 0.4 times the operating wavelength of the antenna. The transmitting antenna forms k wave positions, and the beam directions of each wave position are different. The The k wave positions are divided into i times for scanning, where k is an integer greater than or equal to 2, and i is an integer greater than 0, which solves the problem that the antenna wave position cannot be adaptively scanned and the antenna utilization rate is low, and improves the vehicle angle. Utilization of the transmit antenna in the radar reduces the cost of the automotive corner radar.
Description
technical field [0001] This application relates to the technical field of automotive radar, in particular to array antenna arrangement and automotive corner radar. Background technique [0002] With the rapid development of intelligent driving technology, Advanced Driving Assistant System (ADAS for short) has become an indispensable part of intelligent driving vehicles. Surrounding environment, collect environmental data, identify, detect and track static or dynamic objects, and combine the navigator map data to perform system calculation and analysis, so as to predict possible dangers and effectively increase the comfort and safety of driving . Among them, millimeter-wave radar has become the main sensor of ADAS due to its long detection distance, little environmental impact, low cost, and mature technology. The millimeter-wave radar of existing cars is generally multiple input multiple output (MIMO for short). Antenna. In related technologies, one wave position of millim...
