Problems solved by technology

[0002] At present, in the scenarios of civilian vehicles such as automobiles, the general 24GHz and 77GHz radars have a working bandwidth from 100MHz to 1GHz, and a range resolution from 1.5m to 0.15m. The combined long-range and short-range radar generally has a bandwidth of no more than 500MHz. However, this distance resolution cannot achieve the ability to distinguish small objects such as pedestrians, and the antenna used by the radar does not have broadband characteristics.
[0003] For the above problems, no effective solution has been proposed

Abstract

The invention discloses a radar and a vehicle. The radar includes at least one transmitting antenna for transmitting an electromagnetic wave signal to detect a target object around the radar; at leastone receiving antenna for receiving an echo signal, the echo signal being a signal fed back by the target object around the radar after receiving the electromagnetic wave signal transmitted by the transmitting antenna, and the echo signal carrying information of the target object around the radar; and a conversion module for switching a remote detection mode and a proximity detection mode of theat least one transmitting antenna in an azimuth direction, and switching the remote detection mode and the proximity detection mode of the at least one receiving antenna in the azimuth direction. Theinvention solves the technical problem that the distance resolution of the radar is low in the related art.

Description

technical field [0001] The invention relates to the field of radar, in particular to a radar and a vehicle. Background technique [0002] At present, in the scenarios of civilian vehicles such as automobiles, the general 24GHz and 77GHz radars have a working bandwidth from 100MHz to 1GHz, and a range resolution from 1.5m to 0.15m. The combined long-range and short-range radar generally has a bandwidth of no more than 500MHz. However, this distance resolution cannot achieve the ability to distinguish small objects such as pedestrians, and the antenna used by the radar does not have broadband characteristics. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present invention provide a radar and a vehicle, so as to at least solve the technical problem of low range resolution of the radar in the related art. [0005] According to an aspect of an embodiment of the present invention, a radar is ...
