| 摘 要： | 短波数据传输系统由于设备简单,适用于中、远距离和移动通信,其"中继系统"电离层不易被摧毁,因而占据非常重要的地位。对MIL-STD-188-110B39音并行体制信号格式进行分析,找到存在的薄弱环节。依据灵巧干扰的思想,提出针对载波同步头的灵巧干扰策略。对这种体制存在的弱点实施灵巧干扰,并与单音干扰、多音干扰、宽带噪声干扰和窄带噪声干扰等多种干扰方式进行了对比。通过仿真证实了对符号同步干扰的可行性,对攻击同步系统的灵巧干扰策略提供有力的支撑

| Abstract: | The short-wave transmission system,for being simple in equipment,is suitable for the medium and long distance and mobile communications,and has a very important position because the ＂relay systems＂,the ionosphere,is not easy to be destroyed.In this paper,the signal format of 39-tone MIL-STD-188-110B parallel system is analyzed and the weak process is found.According to the smart jamming criteria,the smart jamming signal which is used to jam the symbol synchronization system is designed.Smart jamming is given to the weak process of the 39-tone MIL-STD-188-110B system and compared with single-tone jamming,multi-tone jamming,noise-jamming and narrowband-jamming.The simulation proves that the smart-jamming method has more advantages than other jamming,and supports the smart jamming to the symbol synchronization. |
