摘　　要：复杂平台天线间耦合度计算是系统级电磁兼容研究的重要课题,给出一种解决复杂平台天线间耦合度问题的新方法——逐级等效法。逐级等效法把原始求解区域分成三个分区逐级求解,在求解一个区时,把上一区的等效源作为此区的激励源,最终求得天线间耦合度。通过此方法降低了每次运算时的计算量,使得许多原来不能计算的问题得到解决。为了验证方法的正确性,举例计算了一平台上天线间的耦合度,结果与矩量法计算的统一模型做了对比。最后以某大型战斗机上两天线间的耦合度为例,用逐级等效法解决了这一普通算法在现有计算机配置下很难计算的问题。Researches of the mutual coupling between antennas on a complex platform have significant significance in electromagnetic compatibility. In.this paper, a new approach for the mutual coupling between antennas on a complex platform is presented, named as Cascade Equivalence Approach （CEA）. in this approach, the original area is divided into three ones and results calculated in the first subarea are regarded as equivalent driving source for next. Compared the results computed by CEA with that by Method Of Moments （MoM） ,they are consistent with each other. A didactic example is included to illustrate the approach,CEA is employed to solve the mutual coupling between two antennas mounted on a large- scale fighter plane which can be hardly solved by other conventional algorithms at currently comouter configuration.
