Claim 11:
12. The method of claim 9, wherein determining the actual target composite angle comprises detecting information indicative of the tracking target in the temporal subset associated with a particular predicted target composite angle of the set, wherein the actual target composite angle is closer to the particular predicted target composite angle than to any other predicted target composite angle of the set, wherein the method further comprises:
based on at least one of: the actual target composite angle or the particular predicted target composite angle, determining a second set of predicted target composite angles;
determining refined Doppler shift information, comprising, for each predicted target composite angle of the second set:
determining a respective shortened temporal subset of the reflected probe signal, wherein a duration of the respective shortened temporal subset is less than the duration of the temporal subset associated with the particular predicted target composite angle; and
determining a Fourier transform, over the respective shortened temporal subset, based on the respective scaled time variable, wherein the respective scaled time variable is scaled by the cosine of the predicted target composite angle; and

based on the refined Doppler shift information, determining a refined target composite angle.
