RADAR APPARATUS

1 . A radar apparatus comprising:

an antenna device comprising two or more antennas, and an antenna attachment device formed with a plurality of faces so that the two or more antennas are attached to the antenna attachment device;

a signal transmission/reception module configured to transmit signals through the two or more antennas, and to receive signals reflected from a neighboring object; and

a signal processing module configured to conduct a signal processing to detect the neighboring object,

wherein the plurality of faces includes two or more antenna attachment faces, and normal vectors respective for the two or more antenna attachment faces take different directions, and

wherein at least one of the signal transmission/reception module and the signal processing module is configured as a circuit on at least one of the plurality of faces formed on the antenna attachment device.

2 . The radar apparatus as claimed in claim 1 , wherein an angle formed by the normal vectors respective for the two or more antenna attachment faces is determined according to a detection angle of each of the two or more antennas attached to the two or more antenna attachment faces.

3 . The radar apparatus as claimed in claim 1 , wherein the radar apparatus is mounted on a vehicle at a mounting angle determined according to a detection angle of each of the two or more antennas attached to the two or more antenna attachment faces.

4 . The radar apparatus as claimed in claim 2 , wherein the detection angle of each of the two or more antennas is a design value determined according to information for a range of the non-detected region.

5 . The radar apparatus as claimed in claim 3 , wherein the detection angle of each of the two or more antennas is a design value determined according to information for a range of the non-detected region.

6 . The radar apparatus as claimed in claim 1 , wherein each of the two or more antennas includes one or more array antennas.
