An electronic device capable of reducing a process associated with a radar search is provided. The electronic device DEVa has a transmitting linear array antenna TXA, a receiving linear array antenna RXA, and a control circuit CTLU for controlling the transmitting linear array antenna TXA and the receiving linear array antenna RXA. The transmitting linear array antenna TXA includes a plurality of transmission antennas TXr[1] to TXr[4] arranged along the Z direction, and transmits a transmission wave. The receiving linear array antenna RXA includes a plurality of reception antennas RXr[1] to RXr[4] arranged along an X direction orthogonal to the Z direction, and receives a reflected wave of a transmission wave.

The disclosure of Japanese Patent Application No. 2018-242717 filed on Dec. 26, 2018 including the specification, drawings and abstract is incorporated herein by reference in its entirety.
The present disclosure relates to an electronic device radar device and a radar control method, for example, an electronic device having a transmission linear array antenna and a receiving linear array antenna, a radar device and a radar control method.
Japanese unexamined Patent Application publication No. 2016/45132 shows a weather radar device having a phased array antenna. The weather radar device controls the phased array antenna to form both a transmission beam having a wide beam width in the elevation direction and a narrow beam width in the azimuth direction, and a transmit beam having a wide beam width in the azimuth direction and a narrow beam width in the elevation direction. As a technique for creating virtual antennas and increasing the amount of transmitted data, MIMO (Multiple Input and Multiple Output) radar is known. The MIMO radar is a technique for creating further four virtual antennas by adding one transmitting antenna to a configuration including, for example, one antenna and four receiving antennas.
FIG. 1A is a plan view showing a schematic configuration example of an electronic device according to the present first embodiment, and FIG. 1B is a plan view showing an equivalent configuration example of FIG. 1A.
FIG. 2 is a schematic diagram showing a configuration example of a control circuit in FIG. 1.
FIGS. 3A and 3B are conceptual diagrams illustrating examples of effects associated with perpendicular arrangement of antennas in the electronic device of FIGS. 1A and 1B.
In the following embodiments, when required for convenience, the description will be made by dividing into a plurality of sections or embodiments, but except when specifically stated, they are not independent of each other, and one of them is related to modified example, detail, supplementary description, or the like of part or all of the other. In the following embodiments, the number of elements or the like (including the number, number, quantity, range, and the like) is not limited to the specific number except the case where it is specified in particular or the case where it is obviously limited to the specific number in principle, and may be a specific number or more or less.
Furthermore, in the following embodiments, it is needless to say that the constituent elements (including element steps and the like) are not necessarily essential except in the case where they are specifically specified and the case where they are considered to be obviously essential in principle. Similarly, in the following embodiments, when referring to the shapes, positional relationships, and the like of components and the like, it is assumed that the shapes and the like are substantially approximate to or similar to the shapes and the like, except for the case in which they are specifically specified and the case in which they are considered to be obvious in principle, and the like. The same applies to the above numerical values and ranges.
Hereinafter, embodiments of the present invention are described in detail with reference to the drawings. In all the drawings for explaining the embodiments, the same members are denoted by the same reference numerals in principle, and repetitive descriptions thereof are omitted.
