摘　　要：基于二维最佳二进阵列,利用逆Gray映射构造了一类四元二维零相关区(ZCZ)阵列集.得到的四元ZCZ阵列集的参数可以达到理论界限,是一类最佳四元ZCZ阵列集.ZCZ阵列集的参数如阵列数目和零相关区大小可以灵活设定.矩形零相关区在行或者列方向上达到最大值.还给出了一类移位序列集的构造方法,通过设定不同参数可以得到多个可用于构造四元ZCZ阵列集的移位序列.Based on binary two dimensional array with ideal auto-correlation, a class of quaternary two dimesional array sets with zero-correlation zone are constructed by using inverse Gray mapping. The proposed quaternary ZCZ array set is optimal accord ing to the theoretical bound,and the parameters of which are flexible.Moverover, a construction of shift sequence sets is presented. Numbers of shift sequences can be comtructed by setting different parameters, and quaternary ZCZ array sets can be proposed corre- spondingly.
