%X Recently, a new technique refered to as the on-surface radiation boundary condition (OSRC) approach was presented to calculatc the electromagnetic scattering by con-vex structures. When the scatterer is with first-order surface discontinuities, the OSRC obtained by this new technique is very inaccurate. Thus there are many limitations about the applica-tion of the OSRC approach. In this paper, the OSRC approach is modified, and a method to deal with the scattering by convex two-dimensional objects with arbitrary singular edges is presented. This method is applied to calculate monostatic and bistatic rader cross-section from convex scatterers with nonsmooth surfaces. The result shows that OSRC approach greatly improves the accuracy of the scattered field prediction.
