摘　　要：针对跳频组网中常见的干扰方式,在分析全频带干扰、部分频带干扰、跟踪干扰的干扰容限的基础上,重点以调制方式为MSK的跳频通信系统为例,对跳频组网中同步捕获回路进行抗干扰性能分析。通过仿真结果表明,增大跳频频点带宽、增加跳频频点数目、提高跳频速率可有效提高跳频通信系统同步捕获回路的抗干扰能力。Focusing on the common jamming on frequency hopping system,the anti-jamming tolerance,which including full-band jamming,partial-band jamming and tracking jamming are analyzed.Taking the frequency hopping communication system with MSK modulation as an example,the anti-jamming performance of the synchronous acquisition loop on FHSS is analyzed.The simulation results show that,by increasing the bandwidth,the frequency hopping number and the frequency hopping rate can improve the synchronous acquisition loops′anti-jamming resistance in the FHSS communication system.
