摘要
通过计算机仿真手段,对作战目标模拟的逼真度进行科学合理的评估,是确保电子对抗仿真试验结果可信性的前提。但是,逼真度评估过程中对不同指标的标准化处理存在诸多困难,如不同指标、不同参数的物理含义和取值区间各不相同,给出容易理解和接受的指标归一化处理方法存在较大难度。针对上述问题,对构成逼真度评估的指标要素进行了分类描述,给出了各类指标的标准化方法及适用条件,解决了评估中由于指标的量纲不同而难以量化的问题,为下一步对指标标准化数值聚合,计算最终目标的逼真度结果提供了基础。
A scientific and reasonable assessment of the fidelity of combat target simulation via computer simulation method lays the foundation of the credibility of electronic countermeasures simulation test results,which,however,faces several troubles in dealing with the normalization of different indexes,such as the different attributes and values among different index factors. As a result,it is much difficult to give an easy acceptable method of normalization for all kinds of indicators. To solve problems,the index for fidelity evaluation is given classified description,the normalizing methods of index and its applicable conditions are also involved,which account for quantization issue by dimension difference of performance index. It provides the basis for the polymerization of index values and calculation of the final fidelity.
