| Abstract: |
| 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. |
