There is a demand to establish measurement techniques that can measure radar cross section (RCS) of electrically and physically large objects with high accuracy. The purpose of this paper is to confirm the RCS measurement accuracy at a real outdoor ground-plane range (GPR), and to verify the effectiveness of an RCS near-field-to-far-field (NF) transformation method for an object having a complicated shape. First, near-field monostatic RCS patterns of a simplified aircraft model are measured in the Fresnel region at a GPR on an outdoor asphalt-surfaced road. It is shown that the measured RCS patterns agree well with those computed by the Method of Moments (MoM). Next, the measured near-field RCS patterns are transformed to far-field one by using the RCS NF transformation method. The predicted far-field RCS patterns agree well with those computed directly by MoM. The practicability of the proposed RCS measurement methodology has been verified experimentally. |
