摘　　要：提出一种新的最佳相关信号,即伪随机屏蔽二进阵列偶,研究了其变换性质、Fourier频谱特性和存在的组合允许条件,运用这些性质和条件可以缩小伪随机屏蔽二进阵列偶的搜索范围,提高计算机搜索的效率.在此基础上编写了计算机搜索算法,搜索出若干体积的伪随机屏蔽二进阵列偶.搜索结果表明伪随机屏蔽二进阵列偶具有较大的存在空间,因而可以应用到工程中.A new perfect correlation signal is proposed, which can be called as pseudorandom punctured binary array pairs. The transform properties,Fourier spectrum characters and combinatorial admissibility conditions of the pseudorandom punctured binary array pairs are studied. By making use of these properties and conditions, the efficiency of searching the pseudorandom punctured binary array pairs can be improved significantly. As a computational illustration, a set of pseudorandom punctured binary array pairs are given. The searching results show that the existent range of pseudorandom punctured binary array pairs is so wide that they are suitable for engineering applications.
