周期及奇周期四相失配阵列

Periodic and odd-periodic quadriphase mismatched filtering arrays

对周期和奇周期四相失配阵列信号进行了研究,给出了两种失配阵列信号的存在条件及构造方法,即折叠法和周期乘法,由此构造的失配阵列信号可以使周期或奇周期相关函数的所有旁瓣为0,从而在实际应用中完全消除旁瓣对系统性能的影响,同时扩展了四相阵列信号的存在空间。

The periodic and odd-periodic quadriphase mismatched filtering arrays are proposed in this paper. Existing conditions of periodic and odd-periodic quadriphase arrays and two construction methods, folding and periodic multiplication, are presented. With such construction, as the quadriphase array size increases, the loss, with respect to the periodic or odd-periodic correlation, converges to zero. The periodic and odd-periodic quadriphase arrays can be applied in an actual system, and the influence of the sidelobes on the system can be overcome.
