摘要
提出了一种改进的振幅多阶量化实现方法，并以线阵为例，对不同的单元数进行了计算。与振幅的完全随机量化相比较表明，在不增加收发组件品种的前提下，这种方法可进一步降低天线的副瓣电平。
An improved realization method for amplitude multistep quantization antenna arrays is proposed. It is illustrated for linear arrays as examples. Tbe computation is done for arrays with various number of elements. It is shown that in comparison to the fully random quantization ,the appropriate random can be used to reduce the sidelobe level of antenna arrays without increasing the types of the transmit-receiving modules.
