对数字通信的新干扰技术——伪冒干扰信号产生技术研究

A New Jamming Technology for Digital Communications——Analysis of the Generation of Adaptive Imitating Jamming Signal

由于数字通信信号具有非常强的抗干扰性能,采用常规的模拟白噪声干扰很难达成有效的干扰效果。伪冒通信干扰技术是一种特别有开发前景的实用数字通信干扰新技术。文章介绍了一种通过确定准固定信号段进行信号识别的新方法。信号段的自回归参数被用来改变横截自回归滤波器的特征。自回归过程的输出序列就可伪冒所接收到的信号,从而对目标通信信号实施有效的伪冒干扰。

It is very difficult to achieve effective Jamming on the digital communication systems with the traditional analogue white noise because of the powerful anti-jamming capabilities of the digital communication signals. The communication imitating jamming technology is a new, potential and very useful jamming method against the digital communication systems. A new method for identifying signal by determining quasi-stationary segments of the jammed signal is presented in the paper. Autoregressive parameters of received signal are applied to change the characteristic of the autoregressive filters. The final output sequence of autoregressive processes could imitate the received signal so that it can be used to implement the effective imitating Jamming on target communication signals.
