Through the operation of confusion and slot number mapping, a frequency hopping sequence can be produced with fine uniformity and less-than-512 arbitrary slot number.

该方法通过混淆运算、频隙映射的方式产生出均匀性好、可用频隙数小于512的任意频隙跳频序列。

Lastly, the method of mapping these fractal surfaces to themselves is proposed to obtain a sequence of fractal surfaces of different time, and then the continuously dynamic ocean surface is simulated.
