  • The iterative physical optic method was used for the programming code to calculate radar cross section (RCS),while the forward-backward algorithm combined with relaxation factor was used to accelerate the convergence and improve operation efficiency.Some sample standard models were calculated to validate the reliability of the code;based on this,the RCS of two-dimensional(2-D) nozzles with different aspect ratios and an axisymmetric nozzle was computed and compared.According to the numerical results,this procedure has high accuracy and versatility,and the RCS of the 2-D nozzle is higher than that of the axisymmetric nozzle in the large angular range.
