Abstract
The method of shooting and bouncing rays has been successfully used to predict the radar cross section (RCS) of electrically large and complex target models. However, this method has a demerit that its prediction time is very long when targets are electrically large and complex. Therefore, we propose the hybrid angular division algorithm (HADA) that accelerates prediction of RCS for electrically large and complex target models. This method improves the angular division algorithm (ADA), by incorporating a more efficient way of dealing with patches on planes that meet at angles between (90 –
