Patent number: 11876582Abstract: Examples disclosed herein relate to a radar system for object identification. The radar system transmitting an azimuth fan beam and incrementing elevation of the beam. The radar system may include a transmit antenna and a receive antenna, each having a plurality of antenna elements arranged in rows and columns. The radar system may include a transceiver coupled to the transmit antenna and the receive antenna, the transceiver configured to control transmit beams having an azimuth fan beam, or an elevation fan beam. The radar system may include a processing unit. In various embodiments, the processing unit may include a digital processing unit; a range Doppler mapping module; and an azimuth detection module coupled to the transceiver. The azimuth detection module may be configured to process received signals and identify an azimuth angle of arrival by correlating signals received at antenna elements in rows of the receive antenna.Type: GrantFiled: July 20, 2021Date of Patent: January 16, 2024Assignee: Metawave CorporationInventors: Abdullah Ahsan Zaidi, Kenneth Ray Carroll, Soren Shams, Maha Achour

Publication number: 20220373643Abstract: 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 framework proposes a two-step solution which first isolates a target to a given range doppler bin and elevation angle by linear receive subarray in the elevation direction. However, the elevation estimate is relatively coarse which is further refined along with a high-resolution estimate of azimuth angle. This is achieved by processing the received data from a 2D sparse antenna array, which are systematically chosen to maximize the resolution in both directions. The compressive sensing algorithm is applied to the 2D sparse received array data which exploits the sparse representation of the underlying signal support.Type: ApplicationFiled: May 6, 2022Publication date: November 24, 2022Inventors: Syed Ali HAMZA, Kenneth Ray CARROLL

Publication number: 20220252721Abstract: Examples disclosed herein relate to a beam steering vehicle radar for object identification. The beam steering vehicle radar includes a beam steering receive antenna having a plurality of antenna elements to generate a radiation beam comprising a main lobe and a plurality of side lobes, at least one guard band antenna to generate a guard band radiation beam, and a perception module coupled to the beam steering receive antenna to detect and identify a first object reflection in the radiation beam. The perception module has a monopulse module to determine a range and angle of arrival for the first object reflection and detect multiple objects upon determining an absence of a second object reflection in the guard band radiation beam.Type: ApplicationFiled: June 2, 2020Publication date: August 11, 2022Inventors: Kenneth Ray Carroll, Maha Achour

Publication number: 20210389447Abstract: In accordance with various implementations, a radar system comprising a non-line of sight (NLOS) module to enhance operation of the radar system is provided. In various embodiments, the NLOS module is a radar repeater module with phase shifters to generate an indication of an object detected in a NLOS area. In various embodiments, the NLOS module includes a reflector structure configured to reflect or redirect radar signals from a train on the tracks into a NLOS area. The NLOS module can include a receive antenna, a transmit antenna configured to transmit one or more received radar signals into a NLOS area, and a phase shifting module for applying a phase shift to a radar signal reflected from an object in the NLOS area that is outside an operational range of the radar unit.Type: ApplicationFiled: June 14, 2021Publication date: December 16, 2021Inventors: Soren SHAMS, Maha ACHOUR, Kenneth Ray CARROLL, Abdullah Ahsan ZAIDI, Taha SHAHVIRDI DIZAJ YEKAN, Narek ROSTOMYAN, Hratchia Tom ZARIAN

Publication number: 20210376464Abstract: A radar system for interacting with navigation targets is provided. The radar system is configured to interact with navigation targets (target devices) that shift the phase of a received radar transmission to generate a phase shifted response signal. Phase shifters (e.g., silicon germanium phase shifters) are designed to assign specific frequency responses from one or more navigation modules to identify target locations. The radar module transmits at a modulated signal at first frequency, each navigation target receives the radar transmission, phase shifts the signal and returns the phase shifted signal. Where two or more navigation targets are used, each will apply a different phase shift to the received radar transmission, wherein the frequency identifies the navigation target devices. In a radar system, the modulated transmission signal is compared to the returned phase shifted signal to determine a frequency difference between the two signals.Type: ApplicationFiled: June 2, 2021Publication date: December 2, 2021Inventors: Narek ROSTOMYAN, Abdullah Ahsan ZAIDI, Kenneth Ray CARROLL, Maha ACHOUR

Publication number: 20210208269Abstract: Examples disclosed herein relate to a radar system and method of angular resolution refinement for use in autonomous vehicles. The method includes transmitting a radio frequency (RF) beam to a surrounding environment with a beamsteering radar system and receiving return RF beams from the surrounding environment. The method also includes generating radar data from the return RF beams and detecting objects from the radar data, and determining a direction of arrival of each of object and determining an angular distance between the objects. The method further includes initiating a guard channel detection based at least on the angular distance and determining gain amplitudes of the return RF beams, and determining a null between the objects from the gain amplitudes and resolving the objects as separate objects based at least on the determined null. The method also includes determining a refined direction of arrival of the objects based at least on the resolved objects.Type: ApplicationFiled: January 6, 2021Publication date: July 8, 2021Inventors: Kenneth Ray Carroll, Kaice Theodore Reilly

Patent number: 10842313Abstract: Systems, methods and cartridges for carbonating or otherwise dissolving gas in a precursor liquid, such as water, to form a beverage. A gas source can be provided in a cartridge which is used to generate gas that is dissolved into the precursor liquid. A beverage medium, such as a powdered drink mix or liquid syrup, may be provided in the same, or a separate cartridge as the gas source and mixed with the precursor liquid to form a beverage. The use of one or more cartridges for the gas source and/or beverage medium may make for an easy to use and mess-free system for making sparkling beverages, e.g., in the consumer's home.Type: GrantFiled: January 16, 2018Date of Patent: November 24, 2020Assignee: BEDFORD SYSTEMS LLCInventors: Thomas J.
