| 摘 要： | 证明了Ｃｏｓｔａｓ阵列的等价类之元数为８或４，仅当Ｃｏｓｔａｓ阵列置换ｆ（ｘ）或ｆ（ｎ－ｘ）的周期为２时，其等价类之元数才为４．同时还证明了广义Ｗｅｌｃｈ构造法，广义Ｇｏｌｏｍｂ构造法分别与基本ｗｅｌｃｈ构造法，基本Ｇｏｌｏｍｂ构造法等价．

| Abstract: | This paper proves that the number of the equivalence classes of Costas Array is 8 or 4, and it's 4 only if the cycle of the permutation f(x) or f(n-x) of Costas Array is 2. Also, this paper proves that the Extended Welch construction is equivalent to the fundamental Welch constrnction, and the Extended Colomb construction is equivalent to the fundamental Colomb construction. |
