Abstract

This research explores the use of a shielded octocopter to function as a two-way field probe for conducting electromagnetic (EM) field measurements at a radar cross section (RCS) range. A high frequency (2–18 GHz) Global RCS assessment of an aluminum shield is conducted to determine the effective cut-off frequency, where the shield no longer provides a consistent RCS profile across each aspect. Upon examining the sector averaging of the targets' RCS, it was determined that the shield's cut-off frequency is approximately 2.8 GHz.
