Systems and methods for simultaneous range-rate unwrapping and outlier removal for radar

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 radar devices;
• group data points of the point cloud information to form at least one segment;
• compute possible true range-rate values for each data point in the at least one segment, each said possible true range-rate value being a function of at least a moduli value contained in the point cloud information and a range-rate value contained in the point cloud information;
• identify a scan window including possible true range-rate values for a largest number of data points;
• determine whether at least two modulus of the data points associated with the possible true range-rate values included in the identified scan window have moduli values that are different by a certain amount;
• determine a new range-rate value for each at least one data point of the at least one segment, when a determination is made that at least two modulus of the data points associated with the possible true range-rate values included in the identified scan window do have moduli values that are different by the certain amount;
• and
• modify the point cloud information in accordance with the new range-rate value.
