Abstract
Delay calibration for digital signal chains of SFCW systems is disclosed. An example calibration method includes receiving a burst with a test pulse, the burst having a duration of L clock cycles; receiving a trigger indicative of a time when the burst was transmitted; generating a digital signal indicative of the received burst; for each of L clock cycles, computing a moving average of a subset of digital samples and an amplitude for each average; identifying one moving average for which the computed amplitude is closest to an expected amplitude; identifying the clock cycle of the identified moving average; and updating at least one delay to be applied in digital signal processing of received bursts based on a difference between the trigger and the identified clock cycle. The delay may be used for selecting digital samples of the received signal that contain valid data for performing further data processing.
