Embodiment Construction

[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that those skilled in the art to which the present invention pertains can be easily implemented. However, the present invention can be implemented in various ways and is not limited to the embodiments described below. Also, in order to clearly describe the present invention, parts irrelevant to the description are omitted in the drawings, and like reference numerals are used throughout the specification for like parts.

[0031] Throughout the specification, when a part is "connected" with other parts, it includes not only the case of "direct connection", but also the case of "electrically connected" with other elements between the two parts. And it should be understood that when a part "includes" a certain element, in the absence of a special description to the contrary, it means that other elements may also be included, rather than excluding other ...

Abstract

A device mounted on a vehicle and detecting an object comprises: a transmission/reception unit that transmits a radar signal to the outside of the vehicle on the basis of a first mode or a second mode having different detection ranges, and receives a radar signal reflected by the object; and a processing unit that, when the first mode is activated, detects the object on the basis of the reflected radar signal, and when the second mode is activated, recognishes the object on the basis of the reflected radar signal.

Description

technical field [0001] The present invention relates to a radar device and method for detecting objects based on multiple patterns. Background technique [0002] Automotive Radar is used to provide the driver with position information of surrounding vehicles and obstacles located in front of, to the side of, or to the rear of the vehicle. In addition, automotive radars are installed on self-driving cars, so that safe driving can be achieved by controlling the vehicles to be able to drive themselves. [0003] Existing automotive radars can predict the angle of objects located on the road by arranging antenna arrays side-by-side along the horizontal axis of the vehicle's driving direction. However, since existing automotive radars have excellent angular resolution capability only in the horizontal direction, there are many difficulties in distinguishing objects. [0004] Recently, as self-driving cars have begun to gain attention, Lidar has begun to be used to distinguish ob...
