摘要
为了阻止电子情报分析探测出雷达的脉冲重复间隔(PRI),从保护雷达PRI的角度出发,分析了电子情报的TOA分选方法,重点讨论了CDIF和PRI变换方法的优缺点,得出了干扰TOA分选的本质要求。通过三个场景的仿真实验的探究,实验结果表明随机脉冲干扰方法不能取得很好的效果,干扰脉冲需要进行有规则的设计。实验表明,干扰脉冲与雷达序列的关联性越强,干扰效果越好。
To protect the pulse repetition interval（ PRI） of radar from electronic intelligence（ELINT） analysis,some methods of sorting pulses trains based on TOA are discussed,specially the advantages and disadvantages of CDIF and PRI transformation. Then three example scenarios are simulated to test the capability of jamming methods. It demonstrated that the way of jamming with random pulse is not very useful,for the jamming pulses should be set regularly. It also shows that the time relationship between the jamming pulses and the radar pulses is more regularly,and then the jamming is more effective.
