Abstract: Graphical Electromagnetic Computing (GRECO) is recognized as the most valuable method of the RCS computation for the high frequency region in real time. To the low RCS target, the effect of creeping wave is remarkable and larger than that of facets and wedges in some cases. Based on the C R spline fitting theory, the problem of computing geodesic has been solved and a practical computing example of Low RCS target fully proved the validity of the method in this paper by using the hybrid method of GRECO and Creeping Wave Theory. Some canonical and practical examples are given. Excellent agreement with the measured data indicates that the method has practical engineering value.
