Abstract
A processor implement method may include determining a target azimuth angle of the target object based on an initial radar signal received through an array antenna of a radar sensor, generating a correction radar signal by correcting a phase of the initial radar signal based on the target azimuth angle, and determining an elevation angle of the target object based on the correction radar signal.
Claims20
A processor-implemented method, the method comprising:
- determining a target azimuth angle of a target object, based on an initial radar signal received through an array antenna of a radar sensor;
- generating a correction radar signal by correcting a phase of the initial radar signal, based on the target azimuth angle;
- and
- determining an elevation angle of the target object, based on the correction radar signal.
1 more element
An apparatus, comprising:
- a processor configured to execute instructions;
- and
- a memory storing the instructions, wherein an execution of the instructions configures the processor to:
- determine a target azimuth angle of a target object, based on an initial radar signal received through an array antenna of a radar sensor,
- generate a correction radar signal by correcting a phase of the initial radar signal, based on the target azimuth angle, and
- determine an elevation angle of the target object, based on the correction radar signal.
3 more elements
