摘要
详细分析了跳频跟踪式干扰实施的原理以及具体过程。针对其在干扰过程中存在的问题,提出了一种利用模拟信号的关联性进行数据置乱的抗跟踪式干扰方法,对这种方法的原理和性能进行了仿真分析。考虑到跳频过程中同步对置乱抗干扰的影响,引入了跳频数据相图结构,并给出了基于相图的跳频置乱抗干扰的实现方法。
The paper presents an anti-interference way of scrambling data based on the correlativity of analog signals through analyzing the theory and the process of FH trapping-jamming,and analyzes the theory and the capability through the emulator.The paper brings forward the phase diagram of the FH data and an achieving way of scrambling data based on the phase diagram in view of the synchronization of FH communication.
