摘要
由于跳频通信系统不仅会受到敌方跟踪干扰的攻击,也会受到己方同一布设区域内其他电台邻频干扰的影响.因此,针对敌我两类干扰同时作用于跳频通信系统的实际,理论分析了复杂干扰条件对跳频通信系统的作用机理,并通过计算机仿真对理论推导结果进行了验证.针对典型跳频电台,以推导得到的旁瓣干扰模型为输入参量,评估了电台在复杂干扰下的中断概率.仿真结果验证了理论分析的有效性和正确性.
The frequency hopping communication system is interfered by follower jamming and adjacent frequency interference in tactical applications.Aiming at the influences of both aspects on the frequency system,the mechanism of action is analyzed through theoretical derivation,and the theoretical results are validated by computer simulation.For typical frequency hopping radios,by taking the model above as the parameter of simulation,the outage probability is evaluated under the communication field conditions.The simulation results verify the effectiveness and the correctness of the theoretical analysis.
