Problems solved by technology

However, the performance of resolution such as medium / long-range radar is degraded and the performance of detection range such as short-range radar is degraded, so its performance cannot be maximized
[0012] Therefore, there is a need to develop a radar device that can detect both medium / long distances and short distances and can be downsized while maintaining a high level of resolution and angular resolution, but conventional radar devices cannot meet these requirements

Embodiment Construction

[0037] Hereinafter, embodiments of the present disclosure will be described with reference to exemplary drawings. In the specification, when adding reference numerals to components throughout the drawings, it should be noted that the same reference numerals refer to the same components even if the components are shown in different drawings. Also, in describing the embodiments of the present disclosure, well-known functions or constructions will not be described in detail since they may unnecessarily obscure the understanding of the present disclosure.

[0038]Also, terms such as 'first', 'second', 'A', 'B', '(a)', and '(b)' may be used to describe components of the present disclosure. These terms are only used to distinguish a component from other components, and thus the nature or order of components indicated by these terms are not limited. It should be understood that when an element is referred to as being "connected to," "combined with," or "coupled to" another element, ...

Abstract

The present provides a radar apparatus and an antenna apparatus for the radar apparatus. Two transmission antennas disposed on both sides of the transmission antenna set may be arranged apart from each other by a predetermined vertical distance in a first direction perpendicular to the ground, and the four receiving antennas may be disposed apart from each other by a predetermined horizontal distance, so that the vertical information and the horizontal information of the object can be easily obtained in the long range detection mode and the short range detection mode.

Description

technical field [0001] The present disclosure relates to a radar device and an antenna device, and more particularly, to a device that includes a multiple-input multiple-output (hereinafter, referred to as "MIMO") antenna and uses the antenna to obtain azimuth angle information and Radar equipment for elevation information. Background technique [0002] Radar equipment for vehicles should have high resolution and angular resolution. For example, automotive radar used to prevent frontal collisions can determine blockages by extracting the angles cut in and out in the path of vehicles traveling forward in adjacent lanes. That is, driver safety can be ensured by reducing false detection of objects and estimating collision situations in cut-in and cut-out using high resolution and angular resolution. [0003] Furthermore, using one antenna system, automotive radars require medium / long-range detection capabilities for sensing objects at long distances over a relatively small an...
