The present disclosure relates to a radar sensor apparatus for a vehicle, a method of detecting an object using the radar sensor apparatus, and an antenna apparatus for the radar sensor apparatus. The antenna apparatus includes N (N is an even number greater than or equal to 4) transmitting antennas and a divider. Since the divider is configured such that a preset value is set on a power ratio that is a ratio of power supplied to each transmitting antenna and a phase ratio that is a ratio of phase of a signal transmitted from each transmitting antenna, it is possible to detect a mid/long range target and a short range target simultaneously.

Radar sensor apparatus for vehicle, object detecting method, and antenna apparatus therefor

The present disclosure relates to an antenna device and a radar including the same. Specifically, the antenna device according to the present disclosure includes: at least one first antenna arranged in one direction and configured to radiate a beam tilted at a first tilt angle; at least one second antenna arranged to be spaced apart from the first antenna and configured to radiate a beam tilted at a second tilt angle; an input/output terminal disposed such that any one of a transmission signal and a reception signal moves therethrough; and a divider comprising a first port connected to the first antenna, a second port connected to the second antenna, and a third port connected to the input/output terminal, wherein the divider is disposed such that a signal transmitted to one of the first port and the second port is transmitted to a remaining one of the first and second port through a first path and a second path and the transmitted signal is isolated in the remaining port.

Antenna device and radar including the same

The present disclosure provides the antenna array and the radar device including at least one first antenna arranged in one direction; at least one second antenna spaced apart from the first antenna; at least one shared antenna arranged between the first antenna and the second antenna; a first input-output terminal connected to the first antenna; a second input-output terminal connected to the second antenna; and a connector including a first port connected to the first antenna, a second port connected to the second antenna, a third port connected to the shared antenna, and a connecting portion connected to the first port, the second port and the third port; wherein a signal input to one of the first port and the second port is transmitted to the other port through a first path and a second path, and wherein the signal passed through the first path and the second path are matched at the other port. According to the present disclosure, it is possible to provide the antenna array and the radar device that can be efficiently disposed in a limited space to maximize spatial advantage.

Antenna array and radar device using thereof

The present invention relates to an apparatus and a method for controlling an alignment of a vehicle radar capable of automatically detecting a vertical angle of a target to perform an alignment in a vertical direction. The apparatus includes: a substrate; a transmitting antenna unit configured to be disposed at one side of the substrate; a receiving antenna unit configured to be disposed at the other side of the substrate; and a vertical angle detection unit configured to detect a vertical angle of a target based on a signal received from the receiving antenna unit, wherein the receiving antenna unit includes: a plurality of first antennas configured to be arranged in a row direction to a surface of the substrate; and a plurality of second antennas configured to be arranged in a column direction to the surface of the substrate.

Apparatus and method for controlling alignment of vehicle radar

The present invention relates to radar and antenna technique, and more particularly, to a radar apparatus and an antenna apparatus having antenna configuration of arranging a plurality of array antennas capable of concentrating antenna gain on a direction for sensing.
