A radar horn antenna in which, to reduce or remove unnecessary echo from a specific angular range such as ground clutter, divergence in axial direction of a horn antenna 8 accommodated in a casing and covered with a radome is asymmetrical with respect to the axis of the horn antenna so that a maximum radiation direction in a radiation pattern of the horn antenna is deviated from front to another and/or gain in the specific angular range is controlled.
