<p><P>PROBLEM TO BE SOLVED: To provide a method and instrument by which the bistatic radar cross-sectional area of an object can be measured easily even in a limited space. <P>SOLUTION: The instrument has a transmission antenna 6 disposed at the focal position of a parabolic reflector 1 and uses a compact range which forms an electromagnetic far field falsely by means of the reflector 1. In the instrument, an object 8 to be measured is rotatably provided in a space facing the reflector 1, and a reception probe 7 is disposed toward the object 8 so that the probe 7 may move around the object 8. The bistatic radar cross-sectional area of the object 8 is measured by rotating the object 8 around a rotating shaft perpendicular to the radiated direction of electromagnetic waves radiated from the reflector 1 and, at the same time, by rotationally moving the reception probe 7 around the rotating shaft. <P>COPYRIGHT: (C)2004,JPO</p> |
