Autonomous moving object

An autonomous moving object comprising:

• a radar sensor mounted on the autonomous moving object and configured to scan a volume in front of the object during a movement of the object along a movement path, 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 along the movement path, 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 evaluating whether the synthetic aperture radar image comprises any amplitude peaks, within a pre-defined set of distances and angles, and
• wherein the controller is configured to, in response to detecting presence of a potential obstacle, output a control command configured to cause a changed movement of the autonomous moving object.
