In this work, an extensive correlation between two commonly used radar cross‐section (RCS) computation techniques, i.e. shooting and bouncing rays (SBR) and multilevel fast multipole method (MLFMM), is performed. Numerical results are compared with the measured data, obtained from an anechoic chamber, for a 1:8 scaled down model of a fighter aircraft. It is ascertained that the SBR method, notwithstanding its numerical simplicity, can provide qualitatively similar and reasonably accurate RCS results for an object of varying complexity.
