Patent number: 10261179Abstract: A radar system has different modes of operation. In one mode, the radar operates as a single-input, multiple output (SIMO) radar system utilizing one transmitted signal from one antenna at a time. Codes with known excellent autocorrelation properties are utilized in this mode. At each receiver the response after correlating with various possible transmitted signals is measured in order to estimate the interference that each transmitter will represent at each receiver. The estimated effect of the interference from one transmitter to a receiver that correlates with a different code is used to mitigate the interference. In another mode, the radar operates as a multi-input, multiple-output (MIMO) radar system utilizing all the antennas at a time. Interference cancellation of the nonideal cross-correlation sidelobes when transmitting in the MIMO mode are employed to remove ghost targets due to unwanted sidelobes.Type: GrantFiled: April 25, 2017Date of Patent: April 16, 2019Assignee: Uhnder, Inc.Inventors: Curtis Davis, Monier Maher, Jean P.

Patent number: 10054672Abstract: An automotive radar system and method transmit a plurality of radar signals into a region, detect reflected radar signals, and convert the reflected radar signals into digital data signals. A plurality of range-Doppler maps for the region are generated from the digital data signals, and the plurality of range-Doppler maps are averaged to generate an averaged range-Doppler map for the region. Data points in the averaged range-Doppler map are analyzed to detect blobs in the averaged range Doppler map. If a blob is detected in the averaged range-Doppler map, the radar detector is indicated to be unblocked.Type: GrantFiled: August 31, 2015Date of Patent: August 21, 2018Assignee: Veoneer US, Inc.Inventors: Matthew Fetterman, Jonathan Preussner, Aret Carlsen

Patent number: 10042041Abstract: A radar system and method in a host system include a radar detector detecting reflected radar signals and converting the reflected radar signals into digital data signals. A motion detector detects motion of the host system and indicates velocity of the host system. A processor receives the digital data signals and processes the digital data signals to categorize the digital data signals into target categories, one of the target categories being an environmental clutter category, the processor associating each of a plurality of processed groups of the digital data signals with a velocity, one of the groups of digital data being associated with a first preselected velocity. When the velocity of the host system changes, if the velocity associated with the one of the groups of digital data of the environmental clutter category has not changed, then the processor indicates that the radar detector is at least partially blocked.Type: GrantFiled: April 28, 2015Date of Patent: August 7, 2018Assignee: Veoneer US, Inc.Inventor: Jonathan Preussner
