collision axis alignment

This article describes the necessary and sufficient condition of the two-dimensional hit array can achieved,as well as NHZ frequency codes back algorithm that based on NHZ hit array,and on this basis,proposed a improve algorithm which to construct th.

为了进一步研究降低跳频通信系统多址干扰的方法和利用跳频方式进行移动目标定位问题,人们提出了采用二维碰撞阵列来研究跳频信号的波形特性。
