Abstract: The use of burst adaptive frequency selection(BAFS) in HF communication network is discussed in this paper.The specifications of BAFS and the advantages of its use in HF network are analyzed.The protocol of BAFS in HF network is designed only partly according to MIL-STD-188-141A,because the basic characteristics of BAFS and CAFS(Continuous AFS) are quite different.Then the performance of this protocol is simultaneously evaluated.Also some schemes optimal in different releases are discussed.
