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.
