摘要
随着无线装备的大量应用,电子战逐渐成为打赢现代战争的关键;提高雷达的抗侦察性能是增强雷达电子对抗的重要手段,而抗分选信号设计能够从根本上增强雷达的抗侦察能力。针对目前在信号侦察领域广泛应用的序列差值直方图算法,从破坏分选算法对信号脉冲重复间隔估计值的角度设计抗分选信号。首先梳理了序列差值直方图分选算法工作步骤,分析了算法对信号分选的关键步骤,然后提出了信号设计的方案,最后进行仿真验证。仿真结果显示所设计的信号可以有效对抗分选算法。
With the extensive application of wireless equipment,electronic warfare is gradually becoming the key to winning modern warfare.Improving the anti-reconnaissance performance of radar has become an important means to enhance radar electronic countermeasures.The design of anti-sorting signals can enhance the anti-reconnaissance capability of radar fundamentally.Aiming at the algorithm of sequential difference histogram,which is widely used in the field of signal reconnaissance,the anti-sorting signal is designed from the perspective of destroying the estimation of signal Pulse Repetition Interval(PRI)by the sorting algorithm.Firstly,the operating steps of the sorting algorithm of sequential difference histogram are summarized,and the key steps of signal sorting by the algorithm are analyzed.Then,the signal design scheme is proposed.Finally,simulation verification is carried out.The simulation results show that the designed signal can effectively counter the sorting algorithm.
