Abstract
The disclosure relates to an autonomous moving object comprising: a radar sensor configured to scan a volume in front of the object, and a radar signal processor configured to: acquire a sequence of radar responses, each radar response of the sequence being acquired at a different position of the autonomous moving object, and perform synthetic aperture radar processing of at least parts of the acquired sequence of radar responses to obtain a synthetic aperture radar image representing response amplitude as a function of at least distance and angle with respect to the radar sensor, the autonomous moving object further comprising: a controller configured to detect presence of a potential obstacle within a pre-defined sub-volume in front of the autonomous moving object by analyzing the synthetic aperture radar image and, in response to detecting presence of a potential obstacle, output a control command configured to cause a changed movement of the autonomous moving object.
