Abstract :
GRECO method is often used in far field RCS studies because of its computational efficiency for electrically large structures. It uses the graphical hardware to greatly reduce the computational resource requirements. However, GRECO method has its limitation because of the limit of graphical hardware. This paper presents the mathematical derivation of the errors caused by the limitation of graphical hardware. Based on the Error analysis, Numerical results are used to compare with the PO method.
