摘要： An emission/reception device is configured for communication between a ground station and a mobile craft which is provided with a retro-reflector configured to modulate a laser beam received along a direction and to return it along the direction, the mobile craft being situated above a backscattering zone, the emission/reception device generating at least two temporally offset emission/reception sequences, each being associated with a laser beam and comprising successive pairs of associated emission and reception phases, the emission phase including emitting a laser beam from the ground station towards the mobile craft, and the reception phase including receiving a laser beam returned by the retro-reflector, each reception phase being deactivated during the transit through the backscattering zone of the laser beam emitted during the associated emission phase.
