N2 - The measurement of the scattering of big targets is difficult, particularly in indoor near-field conditions where there are many interactions between the target and the backdrop.Scattering clutter caused by the ground has a major impact on Radar Cross Section (RCS) measurements.Existing techniques, such as raising the targets and employing materials that absorb, partially alleviate these problems, particularly when dealing with larger targets.However, they do not completely fix them.This study presents a technique in which the object is measured many times at different heights of elevation.This strategy improves measurement accuracy by utilizing vector superposition to mitigate coupling, surpassing the performance of conventional methods.
