%X <p>Analysis of transition feature of frequency hopping (FH) sequence was given for traditional frequency hopping (TFH) and correlated hopping enhances spread spectrum (CHESS) or differential frequency hopping (DFH) systems. It demonstrates that the transition probability distribution (TPD) of FH is very important for performance of both TFH and CHESS system, and that though CHESS can provide non-fixed frequency hopping pattern (FHP) for better anti-interceptions, its anti-jamming performance might be lower than that of TFH systems if its fan-out is not big enough. The proposed method TPD based FHP analysis and interference method does not require exact FHP, therefore it is much easier to implement; furthermore jamming strategy thus jamming efficiency can be dynamically adjusted according to some constraints or obtained TPD on-site.</p>
