The present disclosure relates to an airborne radar notably for a drone. In at least one embodiment, the airborne radar has a first structure and a second structure. The first structure is mechanically attached to an aircraft carrying the radar. The first structure has a degree of rotational freedom relative to the aircraft on a first axis. The second structure is attached to the first structure. The second structure has a degree of rotational freedom relative to the first structure on a second axis converging with the first axis. An antenna is attached to the second structure and configured to receive and send electromagnetic waves. An electronic module configured to process the electromagnetic waves sent or received by the antenna is attached to the second structure.
