跳频技术是扩频通信中的一种抗干扰的实用技术。自适应跳频技术是建立在自动信道质量分析基础上的一种技术,该技术能使跳频通信过程自动避开被干扰的跳频频率点,并以最小的发射功率、最低的被截获概率,达到在无干扰的跳频信道上长时间保持优质的通信。本文介绍这种自适应跳频通信基本原理和关键技术以及在提高数据链抗干扰性能中的应用,并通过计算机仿真论证了其优越性能。
The skip firequency technology is one kind of anti-jamming practical technology in the spread spectrum communication. The self adapt skip firequency technology is one kind of technology building on the automatic information channel quality analysis foundation communications quality. This article introduces the basic principle and critical technology of the self adapt communication as well as the application in raising the data chain anti-jamming function, and demonstrate its superiority ability by way of computer simulation.
