摘要
针对协同问答模式下无线电信号配对关系分析的需求,提出了一种基于信号时间序列匹配的询问应答信号配对方法。该方法提取侦察传感器获取的信号模式、到达时间、节点位置等参数,反向推算信号发射时间序列,通过时序匹配算法对询问和应答信号进行准确配对,从而提取节点间问答关系。计算机仿真验证了方法的有效性,在一定的条件下配对正确率超过95%。
According to the pairing relation analysis requirement between interrogation signal and responsive signal in cooperative question and answer(Q&A)mode,a signals pairing method based on signal time sequence matching is proposed.The method extracts the signal pattern,time series and node position parameters obtained by reconnaissance sensor,reversely calculates the transmitted time sequence of signal,and then pairs the inquiring and responsive signal accurately by time sequence matching algorithm,further extracts the Q&A relationship between targets.The effectiveness of the method is verified by computer simulation.The accuracy of pairing can reach more than 95%under certain conditions.
