Summary:
The Iterative Physical Optics (IPO) method has been developed in 1995 [1] to compute the Radar Cross Section (RCS) of open-ended cavities. This method consists in an iterative resolution of the Magnetic Field Integral Equation (MFIE). Then this method has been extended to targets that are not cavities [2] with good accuracy. In this paper, we present an evolution of the IPO method to compute RCS of targets, taking into account edges' diffractions in the resolution of the MFIE. The Equivalent Currents Method [3-4] is used to compute the diffracted fields.
