Abstract: When sensing is performed in a radio access network, clutter may be removed from echo signals using clutter contributing signals, that may be determined based on clutter calibration matrices and one-dimensional echo signals obtained by transforming multi-dimensional representations of echo signals at least partly into the one-dimensional echo signals. When generating, for example, clutter calibration matrices, sensing results may be transformed into one dimensional vectors, that are arranged to two-dimensional matrices. Vectors associated with clutter components in two-dimensional matrices may be used to obtain the clutter calibration matrices.
