Open publisher page 1 citations

Abstract

The method of pulse is applied to predict the radar cross section ( RCS) of a 3-D target over a frequency band based on Finite Difference Time Domain method( FDTD). The wave is set as gauss pulse, and the transient analysis is completed. At last, the value of the electric field is Fourier transformed to obtained the RCS over a frequency band. The result is consistent with that of literature available. Hence the FDTD program is shown correct and effective. The bistatic RCS of a new kind of plane is computed, and the RCS over a frequency band of different front-wing attack angle are also computed. These results are analyzed.
