A Compressed Best Uniform Approximation for Fast Computation of RCS over Wide Angular-band

摘要：

　　Using the best uniform approximation hybridized with Singular Value Decomposition (BUA-SVD) is proposed to reduce the time requirement for computation of monostatic radar cross-section (RCS).In contrast to our previous work, the best uniform approximation technique is applied to compute the key excitation vectors instead of electric current vectors.Reduction of the number of multiple excitation vectors can lead to significantly reduced computation time.Moreover, with low-rank property,the excitation vectors may be further compressed by SVD,resulting in a more efficient method.SVD can lead to reduce the computational complexity further with the best uniform approximation.Numerical results demonstrate that BUA-SVD is efficient for monostatic RCS calculation with high accuracy.
