Research on RCS of FSS Radome

Abstract

In this paper the RCS simulation and measurement of FSS radome are present. A Pyramid or diamond shape Asandwich radome is designed aim to simplify modeling. The FSS are embedded within the skins of A-sandwich wall. The RCS of radome without FSS and with FSS are both calculated by commercial software. The experiment is conducted that shows agreement with simulation in contour. It is also found that the RCS reduction of radome is significant when absorbing structure is applied. It has been demonstrated that it is possible to control the RCS of FSS radome by suitable design and validate simulation.
