ALEXANDRIA, Va., Dec. 31 -- United States Patent no. 12,510,631, issued on Dec. 30, was assigned to Motional AD LLC (Boston).
"Object detection using radar sensors" was invented by Ting Wang (Santa Monica, Calif.), Yun Lin (Santa Clara, Calif.) and Ken Power (Pittsburgh).
According to the abstract* released by the U.S. Patent & Trademark Office: "Provided are methods for generation of representations of radar data. Some methods described include: receiving ADC raw data of a radar sensor of a vehicle; performing range FFT, Doppler FFT, and azimuth FFT on the ADC raw data; generating a 1D range heat map tensor representing the range FFT, a 2D RD heat map tensor representing a combination of the range FFT and the Doppler FFT, a 2D RA heat ma...
