Abstract
The invention is a pylon for supporting a model above a ground plane for radar cross-section testing using a radar providing a specific frequency range and power distribution above the ground plane. In detail, the pylon comprises a column made of a low dielectric constant foam material having a base end for mounting on the ground plane, a model mounting top end and a generally circular cross-section. The column has an abrupt change in diameter at a point between the ends forming a step and dividing the column into upper and lower tapered portions with each of the portions having a specific diameter range. The step is located at a point on the column such that the power is evenly split between the upper and lower portions and the specific diameter ranges of the portions are selected to maintain a 180-degree phase change in the return signal from each of the portions reducing the RCS of the pylon.
