Abstract

Disclosed are a radar apparatus and an antenna apparatus. In particular, disclosed are a radar apparatus and an antenna apparatus including an antenna structure capable of suppressing a grating lobe while enhancing resolution.

Claims13

Dependent claims

A radar apparatus comprising:

a transmission antenna unit including a plurality of transmission antennas;
a transmission antenna grouping unit configured to group the plurality of transmission antennas by a predetermined number of transmission antenna groups such that the transmission antenna groups by the predetermined number of transmission antenna groups are arranged and formed at a predetermined transmission antenna group interval;
a reception antenna unit including a plurality of reception antennas arranged at a reception antenna interval which is determined based on the number of transmission antenna groups and the transmission antenna group interval;
a signal transmission/reception unit configured to transmit a signal through the transmission antenna groups by the number of the transmission antenna groups and receive a signal when the transmitted signal is reflected through the plurality of reception antennas;
and
an object sensing unit configured to sense an object based on the received signal.
