Abstract
Provided herein is a system and method to determine a heading of a target. The system includes a radar sensor that obtains a snapshot of radar data comprising Doppler velocities and spatial positions of a plurality of detection points of a target, one or more processors, and a memory storing instructions that, when executed by the one or more processors, causes the system to perform conducting a first estimation of a heading of the target based on the spatial positions; conducting a second estimation of the heading of the target based on the Doppler velocities; and obtaining a combined estimation of the heading of the target based on a weighted sum of the first estimation and the second estimation.
Claims20
A computer implemented method performed by one or more processors, comprising:
- obtaining a snapshot of radar data comprising Doppler velocities and spatial positions of a plurality of detection points of a target;
- conducting a first estimation of a heading of the target based on the spatial positions;
- conducting a second estimation of the heading of the target based on the Doppler velocities;
- and
- obtaining a combined estimation of the heading of the target based on a weighted sum of the first estimation and the second estimation.
A system configured to determine a heading of a target, comprising:
- a radar sensor configured to obtain at least a portion of a snapshot of radar data comprising Doppler velocities and spatial positions of a plurality of detection points of a target;
- one or more processors;
- and
- a memory storing instructions that, when executed by the one or more processors, causes the system to perform:
- conducting a first estimation of a heading of the target based on the spatial positions;
- conducting a second estimation of the heading of the target based on the Doppler velocities;
- and
- obtaining a combined estimation of the heading of the target based on a weighted sum of the first estimation and the second estimation.
