摘　　要：提出了两种新的构造低相关区(LCZ)序列偶集的方法.一种方法是基于二元二值周期自相关序列与正交矩阵偶,利用交织技术生成一个长LCZ序列,再将其扩展为一个低相关区序列偶集;另一种方法是基于二元二值周期自相关序列偶与正交矩阵偶,利用交织生成一个长LCZ序列偶,再将其扩展为低相关区序列偶集.对构造方法进行了理论证明和举例.由于LCZ序列偶集的存在范围更广,所以可以为实际的工程应用提供更多的选择.Two new methods of constructing low correlation zone （LCZ） sequence pairs set are proposed. One way to construct the LCZ sequence pairs set is to extend a long LCZ sequence generated with interleaved technique based on binary sequence with two-level periodic autocorrelation and orthogonal matrix pair. Another is to extend a long LCZ sequence pair generated with interleaved technique based on binary sequence pair with two-level periodic autocorrelation and orthogonal matrix pair. The construction methods are theoretically proved and some examples are given. They can give more choices for practical engineering because the existence domain of LCZ sequence pairs is wider.
