  • Patent number: 11835644
    Abstract: Aspects of the disclosure are directed to adaptive correction of radar channel-to-channel time-dependent errors. In accordance with one aspect, the adaptive correction of radar channel-to-channel time-dependent errors includes transforming a digitized data flow to generate a transformed data flow; detecting the transformed data flow to generate a detected data flow; focusing the detected data flow to generate a focused data flow; and aligning the focused data flow to generate a corrected data flow. In one aspect, it may further include performing a direction of arrival (DOA) processing on the corrected data flow to generate a resolved data set, processing the resolved data set to generate a post-processed data set, radiating a transmit radar waveform, capturing a receive radar waveform related to the transmit radar waveform and generating the digitized data flow based on the receive radar waveform.

  • Patent number: 11275170
    Abstract: Aspects of the disclosure are directed to dual processing. Accordingly disclosed are, an apparatus and a method for dual processing for stationary objects and moving objects including generating a first set of range/Doppler images and a second set of range/Doppler images from a radar system, wherein the first set of range/Doppler images is processed over a first processing time and the second set of range/Doppler images is processed over a second processing time; using a first clustering algorithm to generate a first set of range/Doppler/angle object detections based on the first set of range/Doppler images; using a second clustering algorithm to generate a second set of range/Doppler/angle object detections based on the second set of range/Doppler images; and generating a set of range/Doppler/angle object tracks for stationary and moving objects from the first set of range/Doppler/angle object detections and the second set of range/Doppler/angle object detections.
