甚宽频信号波束形成方法

介绍了基于直线阵列的常规相移一时延波束形成理论，分析了直线阵列的指向性以及影响其指向性的因素，并对其空间增益进行了定性分析。在此基础之上，提出了一种根据频率的变化改变基阵各阵元的加权，基于最小均方误差条件下的宽带自适应恒定束宽波束形成方法，在整个工作频带内波束宽度基本保持大致相等，可有效抑制因波束形成带来的频率畸变。文中给出了相应的波束形成仿真结果。

The Method Of Wide-frequency Signal Form Beams ABSTRACT

The theory of forming beam based on beeline array is introduced in this article.The point of beeline array and factors which affecting the point is analyzed ,moreover,qualitative analysis of space plus is gained.On this base,studying a new method of forming beam,which is changing every unit＇s power with the variety of frequency,under the undition of the least average-square error. During the job frequency,the beam width keeps equation approximately.it is good for controlling frequency aberrance.This article gives the relevant emulational result of forming beam.
