干扰节点个数对系统性能的影响研究

Research on the Influence of the Number of Jamming Nodes against System Performance

在无线电干扰的实施过程中,干扰信号的功率对干扰效果的影响至关重要。在信号电平一定的情况下,干扰是否奏效主要取决于接收机输入端干扰信号功率的大小,干扰功率越大,系统干扰效果越好。而要研制高功率的干扰机成本很高,在实际的通信干扰中很难实现。基于此,提出了通过增加干扰节点个数来降低干扰功率的方法,并通过仿真验证了该方案的可行性。

The power of the interference signal makes much effect to its result in the process of radio interterence, when the signat level is fixed,the success of interference lies on the power of interference signals of receiver inlet. The bigger of the power of interference signal,the better of the effect of interference, But it＇s costly to develop interference machine with the nature of high power,ires hard to achieve in the practical communication jamming. So we bring a new idea to reduce the power of machine by adding the number of jamming nodes,and we will validate the scheme by simulation.
