Summary:
Owing to rapid increases of computational abilities in electromagnetic simulators and processing abilities of personal computers, RCS simulations become easy. Many examples of RCS simulations and comparing with measured results were reported [1] and [2]. Authors also had been investigating accurate measurement method and convenient simulation method [3]. Previously, the methods of achieving accuracy were not made clear. In this paper, the procedure of achieving accurate measurement is explained using examples of anechoic chamber. As a RCS target, a simple rocket structure composed of fundamental RCS components such as tip, cylinder and hemisphere parts is employed. As for simulation method, PO and MoM simulation results and computer roads are compared. As examples of accurate small RCS simulations, FEKO and WIPL-D simulation results are compared with measured results.
