Radar apparatus and antenna apparatus therefor
First Claim
1. A radar apparatus, comprising:
- a transmitting antenna set configured to include;
a first transmitting antenna group including a first transmitting antenna elongated in a first direction of vertical directions; and
a second transmitting antenna group including a second transmitting antenna and a third transmitting antenna that are elongated in a second direction opposite to the first direction and spaced from the first transmitting antenna by a first vertical distance;
a receiving antenna set configured to include;
a first receiving antenna group including a first receiving antenna and a second receiving antenna that are elongated in the first direction; and
a second receiving antenna group including a third receiving antenna and a fourth receiving antenna that are elongated in the second direction and spaced from the first receiving antenna group by a second vertical distance;
a transceiver configured to transmit transmission signals through the transmitting antenna set and receive reflection signals reflected from an object through the receiving antenna set; and
a processor obtaining information about the object by processing the received reflection signal,wherein the third receiving antenna and the fourth receiving antenna each include k array antennas, the second transmitting antenna, the third transmitting antenna, the first receiving antenna, and the second receiving antenna each include 2 k array antennas, and the first transmitting antenna includes 4 k array antennas.

Abstract
The present disclosure relates to a radar apparatus and an antenna system for the radar apparatus. A first transmitting antenna group and a first receiving antenna group are constituted by elongating some of a plurality of transmitting antennas and a plurality of receiving antennas in a first direction of vertical directions, a second transmitting antenna group and a second receiving antenna group are constituted by elongating the other antennas in a second direction opposite to the first direction, transmitting antennas to transmit transmission signals and receiving antennas to receive reflection signals reflected from an object are appropriately selected, thereby being able to improve horizontal and vertical angular resolving power in both of mid/long-range sensing and short-range sensing.
