| 摘要: |
| 新型体制多功能雷达可以利用排定信号实现对目标的跟踪，有效分选排定信号是对跟踪目标进行攻击、干扰的基础。针对目前国内缺少对排定信号分选研究的情况，提出了一种排定信号分选算法。首先利用改进的正弦波插值算法提取帧周期，将排定信号从交错脉冲串中分离；其次根据排定信号调制规律确定其调制类型，对脉冲到达时间做一级差确定子周期；最后采用关联规则算法（Apriori）解析其子周期排定顺序。实验结果表明，当脉冲丢失率或脉冲干扰达到40%时，排定信号分选正确率仍可以达到90%以上，面对子周期个数的变化也表现出较强的适应性。 |

| 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 |
