Problems solved by technology

[0005] However, the vehicular radar apparatus according to the related art operates on a separate channel and includes a receiver in order to calculate the elevation angle, and therefore, the azimuth and the elevation angle are calculated separately, resulting in a disadvantage that the size of the vehicular radar apparatus increases

Embodiment Construction

[0034] As is conventional in the respective fields, some exemplary embodiments may be shown in the figures in terms of functional blocks, units and / or modules. Those of ordinary skill in the art will understand that these blocks, units and / or modules are physically implemented by electronic (or optical) circuits such as logic circuits, discrete components, processors, hardwired circuits, memory elements, wiring and the like. When the blocks, units and / or modules are implemented by processors or similar hardware, they can be programmed and controlled using software (eg, code) to perform the various functions discussed herein. Alternatively, each block, unit and / or module may be implemented by dedicated hardware or as a combination of dedicated hardware performing some functions and a processor (eg, one or more programmed processors and associated circuits) performing other functions. Each block, unit and / or module of some exemplary embodiments may be physically divided into two...

Abstract

A vehicle radar apparatus and a method of controlling the vehicle radar apparatus are disclosed. The vehicle radar apparatus comprises a transmission array antenna that radiates a radar signal for forward detection; a reception array antenna that operates at N (N is an integer greater than zero) reception channels for receiving the radar signal that is radiated by the transmission array antenna, reflects from a target, and returns; an azimuth angle estimation unit that estimates an azimuth angle of the target using each non-offset reception channel of the N reception channels; and an elevation angle estimation unit that estimates an elevation angle of the target in a diagonal direction in which each non-offset channel of the N reception channels is tilted with respect to an azimuth angle of an offset reception channel thereof.

Description

[0001] Related Application Cross Reference [0002] This application claims priority from Korean Patent Application No. 10-2019-0141555 filed with the Korean Intellectual Property Office on November 7, 2019, the entire contents of which are incorporated herein by reference. technical field [0003] Embodiments of the present disclosure relate to a vehicular radar device and a method of controlling the vehicular radar device, and more particularly, to a vehicular radar device and a method of controlling the vehicular radar device, which estimate targets at N receiving channels in which a receiving array antenna operates The elevation angle in the diagonal direction in which each non-offset receive channel is tilted relative to the azimuth angle of its offset receive channel. Background technique [0004] Radar is a device that radiates electromagnetic waves toward an object and receives electromagnetic waves reflected from the object to detect the distance to the object and t...
