ALEXANDRIA, Va., Nov. 18 -- United States Patent no. 12,474,463, issued on Nov. 18, was assigned to Utah State University (Logan, Utah).
"Tracking a target using doppler shift" was invented by Todd Moon (Providence, Utah) and Thomas Bradshaw (Albuquerque, N.M.).
According to the abstract* released by the U.S. Patent & Trademark Office: "For tracking a target, a method receives a combined signal comprising a target signal reflected by a target and a transmitter signal not reflected by the target, wherein the transmitter signal is comprised of a plurality of orthogonal frequency division multiplexing (OFDM) subcarrier signals. The method calculates a signal Fourier transform for the combined signal to obtain the complex symbols. The method ...
