摘要
针对联合战术信息分发系统(JTIDS)的扩频和跳频技术能有效增强抗干扰能力的特点,分析得出对其通信频点进行干扰时,宽带干扰信号的最佳干扰带宽为2.1875MHz,单频干扰信号偏移通信信号频率800KHz时干扰效果最佳,并采用Simulink软件对结论进行了验证。所得结论为实际运用多频点阻塞式干扰JTIDS系统时,干扰信号带宽与频率的选择提供了依据。
Although spread spectrum and frequency-hopping technology can enhance the anti-jamming ability of Joint Tactical Information Distribution System （JTIDS）,theoretical analyzes the jamming effect of disturbing JTIDS and gets some valuable conclusion,which could be best applied in the selection of bandwidth and frequency of jamming signals.Simulates the result by Simulink and get that,the best jamming bandwidth is 2.1875MHz and best jamming frequency has 800KHz offset.
