This contribution to the special session in honor of Prof. Rafael Gómez-Martín will address the 30 year development of graphical processing techniques (GRECO) for fast computation of Radar Cross Section (RCS) of electrically large and complex targets. The development of GRECO started in 1988, in the frame of the “Applied research project for the development and validation of numerical methods for RCS prediction, analysis and optimization”, in which I had the pleasure to know Rafael since our groups where participating together in the project. The development of GRECO never stopped, and recently it has been updated by replacing the graphical processing technique for computation of surface reflection and edge diffraction by a hybrid CPU-graphical processing approach. The resulting code has the same accuracy as conventional RCS computation techniques, but detection of shadowed surfaces and edges is one order of magnitude faster than the most efficient O(N logN) implementations.
