Abstract

An autonomous moving object comprising a radar sensor is provided. The radar sensor is configured to, during movement, acquire data sets representing reflections from surface portions located within a distance range, and, at least at a sequence of occasions, illuminate a surface region and acquire a data set representing, for each of a set of distances within said distance range, an amplitude and a phase of reflected radar signals received from surface portions located at said distance. Said surface regions comprise common sub-region illuminated at each of said occasions. A radar signal processor is configured to receive the data sets acquired at each of said sequence of occasions. The received data sets form a collection of data sets, wherein each data set of said collection comprises a data subset pertaining to said common sub-region. A surface classifier processor is configured to output a classification of a surface type of the surface based on said collection of data subsets.
