The invention discloses an array antenna array and a car, wherein the antenna array is a multiple-input multiple-output MIMO antenna, and the MIMO antenna includes: a first transmitting antenna, a second transmitting antenna and a third transmitting antenna arranged in a transverse direction, and The first receiving antenna, the second receiving antenna, the third receiving antenna and the fourth receiving antenna arranged horizontally: the center distance between the first transmitting antenna and the second transmitting antenna along the lateral direction is 2d, the second transmitting antenna and the third transmitting antenna The center distance along the transverse direction is 11d, the center distance between the first receiving antenna and the second receiving antenna along the transverse direction is 3d, the center distance between the second receiving antenna and the third receiving antenna along the transverse direction is 3d, the third receiving antenna and the fourth receiving antenna The center-to-center spacing of the antenna along the lateral direction is 12d, where d is greater than 0.4 times the working wavelength of the antenna, which solves the problem that the high DBF sidelobe of the antenna makes it impossible to distinguish large and small targets in the angular dimension, reduces the antenna sidelobe, and does not need to use super-resolution Under the condition of the algorithm, the angular resolution is improved.
Description
technical field [0001] The present application relates to the technical field of automotive radar, in particular to array antenna arrangement and automobiles. 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 the related art, figure 1 It is a schematic diagram a...
