摘　　要：为了弥补四相正交序列周期短的缺陷,将最佳四相正交序列应用于零相关区(ZCZ,Zero Correlation Zone)序列中,提出一种用交织法构建四相ZCZ序列的方法。首先选择合适的移位序列,经交织变换生成具有更长周期的ZCZ序列,再用正交矩阵将该序列进行扩展而得到新的序列集,实现了最佳四相正交序列和正交矩阵的结合。该方法构造的序列具有更大的周期和较大的容量,从而可以更好地在实际工程中加以利用。In order to compensate the defect of short cycle on quadriphase orthogonal sequence, a method for construction of quadriphase zero correlation zone（ZCZ）sequence based on interleaved technique is proposed. For the best quadriphase orthogonal sequence in the ZCZ sequence, a new ZCZ sequence with longer period is synthesized through intertwined transform with the proper shift sequence, then this sequence is extended by orthogonal matrix, thus to get a new set of sequences and achieve the combination of the best quadriph^se orthogonal sequences and orthogonal matrix. Experiment indicates that the sequence constructed by this method, with longer period and larger capacity, could be fairly applied in the practical engineering.
