Claim 12:
13. The autonomous moving object according to claim 1, wherein the radar sensor is a first radar sensor and the radar signal processor is a first radar signal processor, and wherein said first radar signal processor is configured to acquire a first sequence of radar responses so as to obtain a first synthetic aperture radar image, the autonomous moving object further comprising:
a second radar sensor and a second radar signal processor, said second radar signal processor being configured to acquire a second sequence of radar responses, and perform synthetic aperture radar processing of the acquired second sequence of radar responses to obtain a second synthetic aperture radar image representing response amplitude as a function of distance and angle with respect to the second radar sensor,
wherein the first radar sensor and the second radar sensor are configured to scan at least partly non-overlapping volumes in front of the object, and
wherein the controller being configured to detect presence of the potential obstacle within the pre-defined sub volume by evaluating whether the first synthetic aperture radar image and/or the second synthetic aperture radar image comprise any amplitude peaks within a respective pre-defined set of distances and angles.
