ALEXANDRIA, Va., Oct. 27 -- United States Patent no. 12,775,067, issued on Oct. 27, was assigned to BDCM A2 LLC (Dover, Del.).
"Hybrid sparse subarray design for four-dimensional imaging radar" was invented by Syed Ali Hamza (Villanova, Pa.) and Kenneth Ray Carroll (Huntington Beach, Calif.).
According to the abstract* released by the U.S. Patent & Trademark Office: "Two-dimensional DOA estimation is challenging as the computational and hardware complexity could scale as the square as compared to that of one-dimensional problem. The proposed scheme relies on designing antenna locations and also involves a mix of subarray and digital beamforming to lower the overall system performance and cost by reducing the costly transceiver chains.This...
