Signal integration with transceiver motion compensation

Abstract

A method and apparatus for processing a transceiver signal () detected by a transceiver (). The method includes obtaining (S) a processed signal from the transceiver signal (), the processed signal having frames () corresponding to respective time intervals (t, t, t, t), wherein the frames define bins () configured according to a quantized resolution (dr) of the transceiver signal (). The method further includes obtaining (S) data related to a relative motion of the transceiver () during a time interval (t, t, t, t) and initializing (S) a residual distance to zero. For each frame () and each respective time interval (t, t, t, t) the method further includes determining (S) a shift distance (ds, ds) corresponding to a sum of the residual distance and a distance value (d, d) corresponding to a relative motion of the transceiver () in the respective time interval (t, t, t, t) and rounding (S) the determined shift distance (ds, ds) with respect to the distance resolution (dr) to a rounded shift distance. The method then further includes updating (S) the residual distance based on a difference between the determined shift distance (ds, ds) and the rounded shift distance, and generating (S) an adjusted frame () by shifting the bins () of the frame by the rounded shift distance to account for relative transceiver motion with respect to the object () in the respective time interval. The method finally includes processing (S) the signal by integrating bin values () over the adjusted frames ().
