针对"人在回路"末制导武器通信链路开启时间短和目标运动性强的特点,提出一种组合干扰技术,该技术结合拦阻式干扰、瞄准式干扰和灵巧式干扰的优点,采用分段接入的方式产生干扰信号。首先给出组合干扰技术的干扰策略;然后推导了MPSK信号的错误接收概率,优化了干扰波形;结合目标运动特性,计算了干扰功率;最后建立了同步干扰模型并给出干扰信号脉冲长度。仿真试验表明,组合干扰技术可以提高时间利用率,并且可以集中干扰功率。

In view of the short opening time of communication link and strong movement of target,a combined jamming technique is proposed for man-in-loop terminal guidance weapon.Combined with the advantages of blocking jamming,frequency targeting jamming and smart jamming,the technique produces interference signals by segmental access.Firstly,the jamming strategy of combined jamming technique is given.Then the error receiving probability of MPSK signal is deduced and the jamming waveform is optimized.Combined with the motion characteristics of the target,the power of combined jamming technique is calculated.Finally,a synchronous jamming model is established and the pulse length of the jamming signal is given.Simulation results show that the combined jamming technique can improve the time utilization and concentrate the jamming power.
