Abstract
Systems and methods for operating radar systems. The methods comprise, by a processor: receiving point cloud information generated by at least one radar device and a spatial description for an object; generating a plurality of point cloud segments by grouping data points of the point cloud information based on the spatial description; arranging the point cloud segments in a temporal order to define a radar tentative track; performing dealiasing operations using the radar tentative track to generate tracker initialization information; and using the tracker initialization information to generate a track for the object.
Claims34
A method for operating a radar system, comprising, by a processor:
- receiving point cloud information generated by at least one radar device and a spatial description for an object;
- generating a plurality of point cloud segments by grouping data points of the point cloud information based on the spatial description;
- arranging the point cloud segments in a temporal order to define a radar tentative track;
- performing dealiasing operations using the radar tentative track to generate tracker initialization information;
- and
- using the tracker initialization information to generate a track for the object.
The method according to claim 15, wherein the position consistency dealiasing algorithm is considered successful when the absolute difference between an estimated range-rate and a hypothesis range-rate is greater than a threshold.
The method according to claim 16, wherein the dialiasing operations further comprise determining a true range-rate value when the position consistency dealiasing algorithm is considered successful.
The method according to claim 17, wherein the dialiasing operations further comprise using the true range-rate to generate the tracker initialization information.
A system, comprising:
- a processor;
- and
- a non-transitory computer-readable storage medium comprising programming instructions that are configured to cause the processor to implement a method for operating a radar system, wherein the programming instructions comprise instructions to:
- receive point cloud information generated by at least one radar device and a spatial description for an object;
- generate a plurality of point cloud segments by grouping data points of the point cloud information based on the spatial description;
- arrange the point cloud segments in a temporal order to define a radar tentative track;
- perform dealiasing operations using the radar tentative track to generate tracker initialization information;
- and
- use the tracker initialization information to generate a track for the object.
