摘　　要：将最佳屏蔽阵列偶应用于ZCZ(零相关区)阵列中,提出了一种新的ZCZ阵列偶集的构造方法.通常的ZCZ阵列集构造方法是基于最佳阵列的,而本文是将最佳屏蔽阵列偶和正交矩阵相结合,通过选择适当的移位序列,经交织变换可以生成具有一定体积和零相关区的ZCZ屏蔽阵列偶集.由于最佳屏蔽阵列偶的存在范围较广泛,弥补了最佳周期阵列体积受限的缺陷,因而使用本文的方法构造出的ZCZ屏蔽阵列偶集具有较大的容量,可以更好地满足实际工程的需要.The perfect punctured array pairs are used in a zero correlation zone （ZCZ）,and then a construction method for ZCZ array pairs set is presented. The general construction method of ZCZ array set was based on perfect array, but the proposed construction method is based on perfect punctured array pairs and orthogonal matrix, ZCZ punctured array pairs set with certain volume and zero correlation zone can be synthesized through interleaved transformation when suitable shift sequences are selected. The existent range of perfect punctured array pairs is so wide that they can improve the volume limitation of perfect period correlation array.So with the proposed method,ZCZ punctured array pairs set have larger capacity of ZCZ array set, which can satisfy requirements of engineering applications.
