IFF系统中直接序列扩频抗干扰技术的研究

Research on Anti-Jamming Technology of Direct Sequence Spread Spectrum(DS-SS) of IFF System

文章从IFF系统采取的抗干扰措施角度出发,研究了IFF系统中采用直扩序列扩频抗干扰技术后,干扰机采用阻塞式致盲压制干扰下对IFF抗干扰系统的影响,仿真结果说明了IFF系统采取直扩序列扩频抗干扰措施,不仅有助于提高IFF系统的抗干扰性能,提高通信识别的正确率,而且为IFF系统的今后深入研究与系统设计,以及对抗IFF系统的干扰样式研究与改进等提供重要的理论参考价值。

This article from the IFF system adopts the anti interference measures angle, studied the IFF system used in direct sequence spread spectrum anti-jamming technology, jammer using blocking type blinding jamming interference on the IFF interference system, the simulation results showed that the IFF system adopts DSSS sequence spread spectrum anti-jamming measures, not only help to improve the IFF system＇s anti-jamming performance, improve communication recognition accuracy, but also for the future development of IFF system research and system design, as well as against the interference of IFF system style study and improvement to provide important theoretical reference value.
