摘要
Abstract
The new system multifunctional radar can track the target by using the scheduled signal.The effective sorting of the scheduled signal is the basis of attacking and jamming the tracking target.In view of the lack of research on scheduling signal sorting in China,a scheduling signal sorting algorithm is proposed.Firstly,an improved sine-wave interpolation algorithm is used to extract the frame period and separate the scheduled signal from the interlaced pulse train.Secondly,the modulation type is determined according to the modulation law of the scheduled signal,and the sub-period is determined by the first order difference of the pulse arrival time.Finally,an association rule algorithm(Apriori)is used to resolve the sub-cycle scheduling sequence.The experimental results show that when the pulse loss rate or pulse interference reaches 40%,the sorting accuracy of the scheduled signal can still reach more than 90%,and it also shows strong adaptability in the face of the change of the number of sub-cycles.关键词
