摘要
本文从敌我识别系统所采取的抗干扰措施角度出发,介绍了IFF系统中跳频抗干扰技术的应用原理,并对跳频技术的信号进行了分析。并研究了采用跳频抗干扰技术后,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,通过仿真实验,得出了在模式4的环境中,噪声调幅、调频、调相干扰下误码率的分析数据。仿真结果说明了IFF系统采取跳频抗干扰措施,不仅有助于提高IFF系统的抗干扰性能和较低信号被截获概率,而且为IFF系统今后的深入研究与改进提供了重要的参考价值。
This article from the IFF system adopts the anti-jamming measures angle,This paper introduces the IFF system frequency hopping anti-interference technology applications,and the frequency hopping signal is analyzed.Research on IFF system using frequency hopping anti-jamming technology。Jammer using blocking type blinding jamming to IFF interference system effects,Through the simulation experiment,obtained in model 4 environment,noise amplitude modulation,frequency modulation,phase modulation interference BER analysis data.Simulation results show that IFF system by frequency hopping anti-jamming measures,not only help to improve the IFF system anti-interference performance and low probability of interception signals,and for the IFF system to further study and improvement to provide important reference value.
