# 1.算法描述

superposition+sidelobedown (变量 m 控制第几个null filling，amplitude)

taylor+superposition( imp: 1是左边的null -1还是右边的null，sidelevel，null（）第几个null filling， amplitude）

Chebwin+superposition（m:第几个null filling，flag:1是左边的null，-1是右边的null， sidelevel，amplitude）

Chebwin+Taylor （chebwin sideleve，Taylor sidelevel）
