摘　　要：利用核外算法,将计算机硬盘动态的纳入矩量法求解过程打破内存的限制,同时采用并行计算技术加速矩量法的求解过程。通过某飞机的双站雷达散射截面(RCS)计算,验证了核外算法的正确性。最后,将并行核外高阶矩量法用于机载伞形印刷振子天线阵列辐射特性分析,结果表明,该方法可充分利用计算机的硬盘,扩大矩量法可求解问题的规模。The out-of-core algorithm which dynamically adds hard disks to the solving process of moments(MoM) is utilized to break the memory limitation, and the parallel computing technique is adopted to accelerate the solving process of MoM. The computation of aircrafts' bistatic Radar Cross-Section(RCS) verifies the validity of out-of-core algorithm. The parallel out-of-core higher-order MoM is utilized to analyze the radiation characteristics of airborne umbrella printing oscillator antenna array. The results show that the method can extend the scale of the problems that can be solved by using MoM through taking full advantages of computers' hard disks.
