自動車のフロントラジエータ領域に取り付けるための二次元ビーム走査およびＬ、Ｕ、Ｔ形構造を有するレーダセンサ

Japanese Patent JP7139334

B2

Apparatuses and methods for two-dimensional beam scanning for determining the position of an object in three-dimensional space are provided. An apparatus comprises a multiplicity of transmitters and receivers, which are arranged orthogonal to one another in an L-, U- or T-shaped structure. In one apparatus, the transmission signals are frequency and phase modulated in combination; and in another apparatus a single frequency carrier signal is subject to binary phase modulation. Here, this is a high-frequency encoding with a great code length, which is generated according to the pseudo-random number principle. The received signals, which include information from all transmitters, are decoded and consequently split into sub-signals, which can be assigned to a two-dimensional virtual array. According to the method of digital beamforming, the individual signals of the virtual antenna elements are formed into a plurality of highly focused beams in the horizontal and vertical direction.
