  • The paper focus on the description of the dimensional distribution of the timedomain scattered electromagnetic field around a 2D body and Radar Cross Section ( RCS ).The calculation of electromagnetic field usually conforms with the frequencydomain.A high frequency calculation method is mainly adopted,the calculation of fluid field agrees with timedomain.For the purpose of optimization design computation combining of the fluid field and the electromagnetic field,an integrated timedomain scheme is required.By separating the representative value into positive and negative value,allowance errors can be hold down respectively,the timedomain fluxsplitting method is applied to calculation of RCS in comparison with LaxWendroff Scheme.Therefore,the final results of the two methods were consistent.
