Patent number: 11789138Abstract: Methods and apparatus to implement compact time-frequency division multiplexing for MIMO radar are disclosed. An apparatus includes an antenna array controller to: transmit a first signal via a first transmitter of a radar antenna array, the first signal having a first duration and modulated across a first frequency range; and transmit a second signal via a second transmitter, the second signal having a second duration and modulated across a second frequency range, the first and second durations including an overlapping period of time, the first and second frequency ranges including an overlapping frequency range. The apparatus further includes a signal separation analyzer to: determine a first echo received at a receiver of the radar antenna array corresponds to the first signal; and determine a second echo received at the receiver corresponds to the second signal.Type: GrantFiled: June 27, 2019Date of Patent: October 17, 2023Assignee: INTEL CORPORATIONInventors: Chulong Chen, Saiveena Kesaraju, Moshe Teplitsky, Alon Cohen

Patent number: 11592548Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to improve Doppler velocity estimation. An example apparatus is disclosed including a transmitter to transmit a first sweep signal at a first position in a first block of time during a transmit time sequence pattern, and transmit a second sweep signal at a second position in a second block of time during the transmit time sequence pattern, the second position different than the first position. The example apparatus also includes a velocity analyzer to determine a velocity and a direction of arrival of a target object identified during the transmit time sequence pattern.Type: GrantFiled: September 27, 2019Date of Patent: February 28, 2023Assignee: Intel CorporationInventors: Saiveena Kesaraju, Arnaud Amadjikpe, Chulong Chen

Patent number: 11543519Abstract: A method of collision warning using broad antenna pattern ultra-wide band (UWB) radar includes emitting a first radar ping from a broad beam UWB antenna and receiving a first return signal identifying an object. A first hemisphere with a first radius is determined for the object. A second ping, second return and second hemisphere is defined for the object. At the intersection of the hemispheres, an object ring is defined. The radius of the object ring is compared with the radius of a collision cylinder (e.g., representing a safe distance around a system or device, such as a drone). The object may be identified as posing a collision threat when the radius of the object ring is smaller than the radius of the collision cylinder.Type: GrantFiled: June 28, 2019Date of Patent: January 3, 2023Assignee: Intel CorporationInventors: Richard D. Roberts, Melissa Cowan, Saiveena Kesaraju
