摘要
为了提高对FH/DS通信系统的干扰效率,相继提出了一些新的干扰方法;然而,这些新的干扰方法在FH/DS通信系统每跳驻留时间内仅能干扰其中一小部分.为此,在对FH/DS通信系统研究基础上,重点分析了部分驻留时间干扰对FH/DS通信系统同步的影响.进一步进行了计算机仿真与分析,验证了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.
In order to enhance the jamming efficiency to FH/DS communication systems, some new interference methods have been put forward. However, these new interference methods can interfere only a part of the system during every hop span of the FH/DS communication system. Therefore, based on the research on FH/DS communication systems, the innuence of part time-resident interference on FH/DS communication system synchronization is analyzed in this paper. Computer simulation and analysis have been made, and the results validate the effectiveness of part time-resident interference under certain ratio of jamming-to-signal time-resident.
