中文摘要：

从无尺度网络动力学特征的新角度,研究信息融合网络系统抗毁性问题。针对以往的抗毁性测度指标不适用于复杂信息融合网络抗毁性研究的现状,考虑信息融合系统的时延及战场感知覆盖率等因素,提出一种新的抗毁性测度指标：网络覆盖率。在该指标的基础上对无尺度网络模型的抗毁性进行研究,并分析不同的拓扑改进策略对网络抗毁性的影响。

英文摘要：

The invulnerability of complex information fusion networks is analyzed based on network dynamics. Previous measures of invulnerability are not suitable for study on invulnerability of complex information fusion networks. Network coverage is proposed as a new measure of invulnerability, taked time-delay and battle- field perception coverage into consideration. The scale-free network invulnerability is studied based on this measure. Two strategies of transforming network topology are analyzed.
