摘　　要：在评价相控阵天线质量的传统方法中,往往依据指标主要属性分类成层,容易忽视指标间的复杂联系。针对该问题,从研究指标间的内部关系出发,搭建了反映相控阵天线质量特性的解释结构模型。并着重探讨如何分析该模型,将模型分为"一对多"和"多对一"两种基本结构,利用D-S理论、模糊分配及Einstain算子详细叙述了这两种结构的求解过程。最后,以该方法在某型远海机动水文监测雷达天线中的具体应用,验证了ISM模型从建立到分析整个过程的可行性和准确性。The traditional quality evaluation methods of array antennas usually divide indexes into several layers, which do not concentrate the complex relationships among them, but only consult through their main properties. Aiming at the problem, beginning with discuss internal relationships between indexes, Interpretative Structural Model reflecting quality properties of array antennas is built. The main content is how to analyze the model. A combination of D-S theory, Fuzzy distribution and Einstain operator is used to detail solution of two basic structure, i.e. ＂one-to-many＂ structure and ＂many-to-one＂ structure, which are collected from the model. Finally, an example of pelagic hydrological monitoring mobile radar antenna truly verifies feasibility and veracity of the whole process from establishment to analysis of ISM model.
