| 摘 要： | 在通信系统抗干扰技术研究方面,大多采用跳频和扩频的方式,并且不断追求更高的跳速,以提高对方的干扰成本。但对于某些通信系统,由于受天线带宽窄和通信速率低的限制,无法实现高速跳频,所以必须寻求一种具有强抗跟踪干扰能力的跳频体制,以提高这些系统的抗干扰能力。主要针对跟踪式噪声干扰、跟踪式单频干扰、跟踪式噪声与单频组合干扰条件下,对R4FSK/FH的抗干扰性能进行理论分析,探讨其应用于实践的可行性。

| Abstract: | Communication systems conventionally adopt frequency hopping and spread spectrum as the anti-jamming means.And the enhancement of the hopping speed would raise the interference cost of the other side.However,for systems which could not achieve high-speed hopping because of low rate and narrow bandwidth of antenna,it is necessary to find a hopping mode with strong anti-track-interference capability and improve the anti-jamming ability of these systems.The paper mainly gives a theoretical analysis on anti-jamming performance of R4FSK/FH in the background conditions of tracking noise,track-style single-frequency interference,and combined tracking noise and single-frequency interference,and explores the feasibility of its application to practice. |
