| 为了解和掌握典型作战环境下弹载通信干扰机的干扰效果，利用OPNET仿真平台建立弹载通信干扰模型，并在被干扰对象进程中刻画了典型作战环境下的信号传输模型，最后当跳频电台的发射天线高架时，对东南沿海和西南边境等两种典型作战环境进行了仿真验证。仿真结果表明:东南沿海环境下，干扰机下降过程中受到障碍物的阻挡时，干扰信号无法到达部分电台的接收端，导致电台接收端的信噪比有所提高；西南边境环境下，干扰机下降过程中由于山区地形的遮挡，对超短波电台的干扰信号阻挡较多，干扰效果不明显，而对短波电台的阻挡较少，被干扰的程度较大，使得短波电台出现了丢包。随着干扰机的进一步下降，对短波电台的干扰信号也被阻挡，使得对短波的干扰程度降低，其丢包率和误码率均逐步降低。相关结论对充分发挥典型作战环境下弹载通信干扰机的作战效能具有借鉴意义。 |
| 英文摘要: |
| To understand and master the jamming effect of projectile-carried communication in typical combat environment,the projectile-carried communication jamming model was constructed in OPNET simulation platform and the signal transmission model in typical combat environment was depicted in the process of the jammed object. Finally, when the transmitting antenna of frequency hopping radio was high elevated, two typical combat environments, such as southeast coast and southwest border, were simulated and verified. The simulation results showed that in the southeast coastal environment, when the jammer was blocked by obstacles during the descent process, the jamming signal cannot reach the some radio receivers, which caused the increase of signal-to-noise ratio at the radio receivers; in the southwest border environment, due to the occlusion of mountain terrain during the descent process, the jammer blocked the VHF radio signal more, and the jamming effect was not obvious; but blocked the HF radio less, and the degree of jamming was larger, which made the HF radio lose its packet. With the further decrease of jammer, the jamming signal to HF radio was blocked, which reduced the degree of jamming to HF, and decreased the packet loss rate and bit error rate. Relevant conclusions can be used for reference to give full play to the operational efficiency of projectile-carried communication jammer in typical combat environment. |
