摘　　要：提出了一种新的序列偶———非等周期ZCZ序列偶的概念。介绍了该序列偶在几种基本变换情况下的性质,在此基础上引入了集合的概念,并介绍了偶集合的基本性质。研究了这种偶的谱特性,应用这些谱特性给出了这中偶的重量分布情况及存在的必要条件。非等周期ZCZ序列偶的提出,为工程应用提供了更广泛的信号选择。In this paper, a new concept of sequence pairs-unequal period ZCZ sequence pairs is defined and some characteristics of the sequence pairs are discussed under a few basic transformation circumstances. A new family concept considering unequal period ZCZ complementary sequence pairs is defined. Some characteristics of the sequence pairs family are discussed. The Fourier spectrum characteristics of this sequence pairs are also studied. Based on the spectrum characteristics, the weight distribution of this pairs is discussed. That is the existent essential condition of this pairs. The unequal period ZCZ sequence pairs provide a more extensive signal choice for the engineering application.
