ABSTRACT:
The subject matter disclosed herein relates to techniques for estimating a speed of an object that transmits a signal at a carrier frequency. An apparatus and method disclosed herein includes receiving at an array of multiple antenna elements a radio frequency signal transmitted by a moving object; and estimating a speed of said moving object based, at least in part, on a spatial cross-correlation among characteristics of signals received at individual ones of said multiple antenna elements.
