摘　　要：时分干扰信号是时分多目标干扰和脉冲干扰中干扰信号的基本形式,对于其性能的分析很有意义。通过理论分析和软件仿真得到了时分噪声调频干扰信号的功率谱密度表达式,分析了其干扰功率和干扰带宽,得出时分干扰信号的干扰功率仅和其占空比有关,干扰带宽受干扰脉冲宽度和噪声调频有效调制带宽的影响。该分析方法同样适用于其他形式的时分干扰信号。Time-division-jamming-signal is the fundamental form of the time division multi-target jamming and pulse jamming.It is of great significance to analyze its performance.The power spectrum density function of the time division noise FM jamming signal is attained here through theoretical analysis and simulation.And the jamming bandwidth and jamming power are analyzed.Its jamming power is just subject to the duty ratio,while its jamming bandwidth is dependent on the jamming pulse width and noise FM's effective modulation bandwidth.The analysis method here is also applicable to other time division jamming signals.
