  • 摘要: 特征基函數(shù)法是分析目標(biāo)寬角度電磁散射特性的有效方法之一,但在構(gòu)造特征基函數(shù)時(shí),設(shè)置的入射波激勵(lì)包含大量的冗余信息,大大降低了特征基函數(shù)的構(gòu)造效率;另外在分析復(fù)雜目標(biāo)時(shí),在增加激勵(lì)數(shù)目的情況下,僅應(yīng)用主要特征基函數(shù)并不能顯著提高計(jì)算精度。針對(duì)這些問(wèn)題,該文對(duì)特征基函數(shù)構(gòu)造方法進(jìn)行改進(jìn),首先采用奇異值分解技術(shù)對(duì)激勵(lì)矩陣進(jìn)行壓縮去除冗余信息,減少求解矩陣方程的次數(shù);其次充分考慮子域之間的互耦作用,將主要特征基函數(shù)與次要特征基函數(shù)融合,得到改進(jìn)的主要特征基函數(shù)。數(shù)值計(jì)算結(jié)果表明:與傳統(tǒng)方法相比,該方法具有更高的計(jì)算效率和計(jì)算精度。
