Abstract

The invention discloses a radar anti-interference antenna, method and system, and a vehicle. The radar anti-interference antenna includes a transmitting antenna and a receiving antenna, wherein the transmitting antenna includes a first transmitting antenna, a second transmitting antenna, and a Lambda / 4 directional coupler; the polarization directions of the first transmitting antenna and the second transmitting antenna are orthogonal to each other; the Lambda / 4 directional coupler further includes a first input port, a second input port, a first output port, and a second output port; the firstinput port and the second input port are isolated from each other; the first output port is connected to the first transmitting antenna, and the second output port is connected to the second transmitting antenna; the receiving antenna includes a first receiving antenna and a second receiving antenna; the polarization directions of the first receiving antenna and the second receiving antenna are orthogonal to each other; the first transmitting antenna and the first receiving antenna have the same polarization direction; and the second transmitting antenna and the second receiving antenna havethe same polarization direction. The radar anti-interference antenna solves the problem of mutual interference between vehicle radars.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of automobile safety control, in particular to a radar antenna, a method, a system and a vehicle. Background technique [0002] Automotive millimeter-wave radar is a safe driving assistance sensor, which is currently widely used in safety assistance systems such as lane change assistance, blind spot monitoring, automatic cruise and automatic driving. As the number of cars increases year by year, there are more and more vehicles equipped with automotive millimeter-wave radars, which makes it very likely that you will encounter cars that are also equipped with millimeter-wave radars when driving a vehicle. In some scenarios, the millimeter-wave radars installed on multiple vehicles will interact with each other, resulting in a decrease in the detection performance of the millimeter-wave radar or even a wrong detection, which poses a great risk to the safe driving of the vehicle. The ...
