摘要

摘要: 跳频技术是目前通信领域应用非常广泛的一种通信方式。当跳速足够高、跳频带宽足够宽时，常规的干扰方法往往难以奏效。提出利用脉冲干扰信号对跳频信号的同步部分进行干扰的方法，并在MATLAB中建立典型跳频通信系统的信号级干扰仿真系统，采用脉冲信号进行干扰仿真研究。结果表明，脉冲干扰信号是一种对抗跳频通信的可行方式，针对跳频通信系统的同步部分进行干扰可以有效降低对脉冲信号源的综合指标要求。

Abstract: Frequency-hopping(FH) is widely used in many ways. FH communication is a kind of communication system with strong anti-jamming capability. This paper discusses a new algorithm to block FH communication system by using pulse-jamming signal. Meanwhile, jamming effects of pulse-jamming signal on synchronization to FH communication system is simulated in MATLAB. The simulation results show the validity of pulse-jamming on FH communication system and jamming energy can be effectively reduced by attacking synchronization of FH communication system.
