将Maehly近似下的最佳均匀有理逼近应用于矩方法(MoM)，得到了较宽频段的雷达散射截面(RCS)。研究了三维任意形状理想导电(PEC)体的数值计算结果。与渐近波形估计(AWE)技术相比，该技术在更宽的频带内具有更高的效率，所需存储空间更小。？？2007 Wiley期刊，Inc.微波OPT Technol Lett 49：1144-1146,2007；在线发表在Wiley InterScience(www.intercience.wiley.com)上。DOI.10.1002/MOP.22367
The best uniform rational approximation, performed by the Maehly approximation, is applied to the method of moments (MOM) to obtain the radar cross section (RCS) over a broad frequency band. Numerical results for three dimensional arbitrarily shaped perfectly electrically conducting (PEC) bodies are considered. Compared with the asymptotic waveform evaluation (AWE) technique, the presented technique is found to be efficient in much broader frequency band with lower memory required. © 2007 Wiley Periodicals, Inc.
