Title:

RECEIVER, AND RADAR APPARATUS, VEHICLE, AND COMMUNICATION SYSTEM PROVIDED WITH RECEIVER

Document Type and Number:

WIPO Patent Application WO/2020/261834

Kind Code:

A1

Abstract:

Provided are a receiver that can accurately estimate the angle of an incoming wave in a two-dimensional direction by an AF method, and a radar apparatus, a vehicle, and a communication system provided with the receiver. A receiver 1 is provided with a first linear array antenna 2, a second linear array antenna 3, and an arithmetic device 4. The first linear array antenna 2 has four first reception antennas 20-23, the quantity of which being more by two than the quantity of incoming waves P, Q equaling two and which are arranged at equal intervals L on a single straight line. The second linear array antenna 3 has four second reception antennas 30-33 arranged, at a height different from that of the first linear array antennas 2, at equal intervals L on a single straight line parallel to the straight line where the first linear array antennas 2 are arranged. The arithmetic device 4 is provided with an azimuth angle phase difference first estimation unit 4a, an azimuth angle phase difference second estimation unit 4b, an incoming wave signal first estimation unit 4c, an incoming wave signal second estimation unit 4d, an elevation angle phase difference estimation unit 4e, and an incoming direction two-dimensional estimation unit 4f.
