摘要
扫频式干扰、更高跳速碰撞干扰等新的干扰方法成为跳频通信系统电子对抗领域中又一重要研究方向。在跳频通信系统每跳驻留时间内,这些新的干扰方法仅能干扰其中一小部分。为此,在对跳频通信系统研究基础上,重点分析了部分驻留时间干扰对跳频通信系统同步及跟踪的影响。进一步进行了仿真与分析,结果表明在一定干信驻留时间比情况下,部分驻留时间干扰的有效性,从而为针对跳频通信系统进行对抗提供相关方法。
New interference methods, such as sweeping frequency interference and faster-hop-collision interference, become a new focus of electronic countermeasures to FH communication systems. During the every hop span of FH communication systems, these new methods of interference can only work on a part of it. Therefore, based on researching FH communication systems, the influence of part time-resident interference on FH communication＇ s synchronization and its tracking has been mainly analyzed. And more, a computer simulation has been made and the results indicate the validity of part time-resident interference under the certain ratio of jamming-to-signal time-resident, consequently, it may provide concerned methods for countermining FH communication systems.
