二元喷管简化模型的RCS高于轴对称喷管简化模型的RCS.

Abstract

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.
