A mounting structure for supporting an object (i.e. aircraft or test model of an aircraft) 102 during a radar cross section measurement, comprising a base 108 configured to rotate about a first axis, at least one elongate support 112 extending upwardly from the base 108 to a tip configured to receive the object 102, and at least one shroud 110, housing at least a portion of the elongate support 112, configured to rotate about a second axis, the second axis being substantially parallel to the first axis, the rotation of the shroud 110 about the second axis being in a direction that is opposite to the rotation of the base 108 about the first axis, where the rotational speeds may be substantially equal. The shroud may be at least partially coated in a radar absorbent material (RAM), and may comprise a tapered portion and a tear-drop shaped cross section. There may also be provided one or more radar antennas mounted within a moveable and rotatable measurement module 116, coupled to a frame 114. |
