  • On-chip noise reduction and power consumption distribution for a radar system
    Patent number: 11531085
    Abstract: A radar system may include a set of analog components to perform one or more radio frequency (RF) operations during an active radar phase of the radar system. The radar system may include a set of digital components to perform one or more digital processing operations during at least a digital processing phase of the radar system. The one or more digital processing operations may be performed such that performance of the one or more digital processing operations does not overlap performance of a substantive portion of the one or more RF operations.

  • METHODS AND APPARATUSES FOR TESTING ONE OR MORE RECEPTION PATHS IN A RADAR RECEIVER
    Publication number: 20220113375
    Abstract: A method for testing at least one reception path in a radar receiver is provided. The reception path contains a mixer and a downstream signal processing circuit. The method includes injecting a test signal into the radar reception path so that at least a first test tone having a first test tone frequency in a passband of the downstream signal processing circuit and a second test tone having a second test tone frequency outside the passband are present on the radar reception path downstream of the mixer; and determining a characteristic of the radar reception path based on a first characteristic of a baseband signal at the first test tone frequency and a second characteristic of the baseband signal at the second test tone frequency.

  • Methods and apparatuses for testing one or more reception paths in a radar receiver
    Patent number: 11269055
    Abstract: A method for testing at least one reception path in a radar receiver is provided. The reception path contains a mixer and a downstream signal processing circuit. The method involves injecting a test signal into the reception path, so that at least a first test tone having a frequency in a passband of the signal processing circuit and a second test tone having a frequency outside the passband are present on the reception path downstream of the mixer. Further, the method involves tapping off a baseband signal, generated by the signal processing circuit, from the reception path, the baseband signal being based on the test signal.
