Systems and methods for range-rate dealiasing using position consistency

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 first point cloud information generated by a first radar device, second point cloud information from a second radar device, and a spatial description for an object that was detected by the radar system, the first and second radar devices having different locations in the radar system;
• generate a plurality of point cloud segments by grouping data points of the first point cloud information and data points of the second 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, where the dealiasing operations use, as inputs to a dealiasing algorithm, an average range-rate value and an average velocity ambiguity value for each said point cloud segment and said radar tentative track;
• and
• use the tracker initialization information to generate a track for the object.

A non-transitory computer-readable medium that stores instructions that are configured to, when executed by at least one computing device, cause the at least one computing device to perform operations comprising:

• receiving first point cloud information generated by a first radar device, second point cloud information from a second radar device, and a spatial description for an object that was detected by the radar system, the first and second radar devices having different locations in the radar system;
• generating a plurality of point cloud segments by grouping data points of the first point cloud information and data points of the second 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, where the dealiasing operations use, as inputs to a dealiasing algorithm, an average range-rate value and an average velocity ambiguity value for each said point cloud segment and said radar tentative track;
• and
• using the tracker initialization information to generate a track for the object.
