ALEXANDRIA, Va., June 16 -- United States Patent no. 12,656,483, issued on June 16, was assigned to Aptiv Technologies AG (Schaffhausen, Switzerland).
"Signal modeling for unambiguous range rate estimation" was invented by Boyi Gao (Westfield, Ind.).
According to the abstract* released by the U.S. Patent & Trademark Office: "This document describes interleaving chirps for unambiguous range rate estimation. A signal model quickly and unambiguously estimates range rates for any chirp within one frame. During each frame, a transmission of radar signals is caused by interleaving two different groups of chirps (e.g., up-chirps and down-chirps) in an ordered sequence. This unique pattern of chirps enables the signal model to compute an ambiguit...
