Classification: CPC G  H | IPC G  H

Claim 14:
15. A method for Doppler-enhanced radar tracking, comprising:
receiving egovelocity data;
transmitting a probe signal;
in response to reflection of the probe signal by a tracking target, at a radar array comprising a first plurality of radar elements positioned substantially along a first radar axis, receiving a reflected probe signal, wherein the tracking target and radar array cooperatively define a target vector from the radar array to the tracking target;
based on the reflected probe signal, determining Doppler shift information; and
based on the reflected probe signal, the Doppler shift information and the egovelocity data, determining an actual target composite angle; wherein
(i) the actual target composite angle is an angle between the target vector and a composite reference vector,
(ii) determining the Doppler shift information comprises:
determining a set of predicted target composite angles; and
for each predicted target composite angle of the set, determining a Fourier transform based on a respective scaled time variable, and

(iii) the respective scaled time variable is determined based on the predicted target composite angle.
