1. A method for Doppler-enhanced radar tracking comprising the steps of:
transmitting a probe signal from a radar array;
generating reflected data in response to a reflection of said probe signal from a target received by said radar array;
determining (i) a range of said target from said radar array and (ii) Doppler shift information each in response to said reflected data; and
determining an actual target composite angle in response to (i) said reflected data and (ii) said Doppler shift information, wherein
(a) said actual target composite angle is an angle between a target vector from said radar array to said target and a composite reference vector, and
(b) determining said Doppler shift information comprises
(I) determining predicted target composite angles, and
(II) determining respective frequency domain outputs for each of said predicted target composite angles.
