1. A method for processing a transceiver signal detected by a transceiver, the method comprising the steps of:
obtaining a processed signal from the transceiver signal, the processed signal comprising frames corresponding to respective time intervals, wherein the frames comprise bins configured according to a distance resolution of the transceiver signal;
obtaining data related to a relative motion of the transceiver with respect to an object in a field of view of the transceiver during the respective time intervals;
initializing a residual distance to zero; and, for each of the frames and each of the respective time intervals;
determining a shift distance corresponding to a sum of a residual distance and a distance value corresponding to the relative motion of the transceiver with respect to the object in the respective time intervals;
rounding the determined shift distance with respect to the distance resolution to a rounded shift distance;
updating the residual distance based on a difference between the determined shift distance and the rounded shift distance;
generating an adjusted frame by shifting the bins of the frames by the rounded shift distance to account for the relative motion of the transceiver with respect to the object in the respective time intervals; and
processing the signal by integrating values of the bins over the adjusted frames.
