英语语法分析

It is the key technology for design of the constant beamwidth array to calculate the weight matrix.

恒定束宽加权矩阵的获得方法是设计此类声纳基阵的技术关键。

With the aid of a computer, curves of beamwidth and side lobe versus the antenna parameters are plotted.

并借助计算机绘出了主瓣宽度和副瓣电平与天线主要参数的关系曲线；

Adopting this plan, it needs not to change beamwidth and there needs no common optical sys-tem for receiving and transmitting.

此方案无须要求通信系统具有能实现宽窄波束变换的光学系统，也不用预先解决收发天线共用的问题。
