摘要
针对当前分选算法中普遍存在增批、漏批的问题,提出了基于上升沿波形配对的分选方法。该方法通过Hilbert法提取辐射源信号的包络波形,并采用三次样条插值法进行拟合,提取具有指纹特性的包络上升沿波形特征,利用Hausdorff距离函数作为相似性度量的方法进行波形配对。通过三组实验,验证了基于上升沿波形配对分选方法的有效性,以及上升沿波形的选择和采样点数对该方法的影响。
Aiming at the problem of increasing batch and missing batch in current sorting algorithm, a method based on the matching of rising edge waveform is proposed. By using the method of Hilbert extraction waveform in the envelope of the signal source, radiation, and fitted by cubic spline interpolation method, the method extracts fingerprint characteristics of en-velope rise along the waveform characteristics, as the similarity measure method of waveform matching using Hausdorff dis-tance function Based on three sets of experiments the effectiveness of the method is verified, and the influence of the selec-tion of the rising edge and the sampling points on the method is verified.
