ABSTRACT:
The disclosure relates to guidance devices on board autonomous vehicles or robots which have to move about notably in environments that are inaccessible or dangerous to human beings. Disclosed is a device for the detection of the environment, and the positioning and/or the guidance of a mobile vehicle on the ground, of the type comprising, firstly, means for the generation and transmission of a signal that can be reflected by a fixed obstacle and, secondly, means for the reception and processing of the signal reflected by said fixed obstacle, said processing means enabling the recognition of the environment and/or the guidance of said autonomous mobile vehicle, said transmitted signal being a millimetric wave radar signal and said transmission and reception means cooperating with a rotary antenna having a 360.degree. rotation in azimuth.
