摘　　要：针对多发弹丸抛射多套弹载通信干扰机覆盖全频段难的问题,提出一种“双发射”模式弹载通信干扰机设计方案。从节点、进程和报文等三个方面阐述了“双发射”模式弹载通信干扰系统的模型构建方法,详细说明了节点参数设置过程,最后在OPNET平台上对电台天线低架和天线高架等两种场景进行了仿真验证。结果表明:当电台天线低架时,通信电台的信噪比均低于接收灵敏度,导致电台间的广播报文无法正确接收;当电台天线高架时,部分电台的跳频图案与干扰机周期性扫频的重合次数相对较高,误码率和丢包率较高。研究结果能够为“双发射”模式弹载通信干扰机的设计和研制提供理论支撑。To solve the problem that multiple projectiles were needed to eject multiple sets of projectile-carried communication jammers to cover the whole frequency band,a design scheme of projectile-carried communication jammer based on“dual transmission”mode was proposed.The model construction method of“dual transmission”mode projectile-carried communication jamming system was elaborated from three aspects:node,process and message on OPNET platform.The process of setting parameters of nodes was described in detail.Two scenarios such as high antenna elevation and low antenna elevation of radio were illustrated.The results showed that when the antenna elevation was low,the signal-to-noise ratio of the communication radio was lower than the receiving sensitivity,which resulted in the inaccurate reception of broadcasting messages between radios;when the antenna elevation was high,the frequency hopping pattern of some stations relatively high coincided with the periodic sweep frequency of the jammer,and the bit error rate and packet loss rate were higher.Relevant conclusions can provide reference for the design and development of the“dual transmission”mode projectile-carried communication jammer.
