熟悉数值方法在matlab中的运用，灵活运用各类绘图函数，边学边用，加强对数值方法的认识。(Familiar with numerical methods in matlab in the use of flexible use of various types of drawing functions, learning while using, to enhance understanding of numerical methods.)

本论文的工作是对近场圆形阵列宽带信号进行处理，获得目标/焦点位置增益输出， 预先定义宽带信号阻带的旁瓣衰减大小以及感兴趣频域内的恒定波束宽带模式。本文使 用不同的方法解决这个设计问题，该问题分为两部分，第一部分解决频域内的模型设计， 第二部分给出时域内的结果。仿真结果表明解决方法的有效性。 (This thesis work is a circular array of broadband near-field signal is processed to obtain the target/focus position gain output, Pre-defined stopband sidelobe wideband signal attenuation constant beam size and frequency domain of interest wideband mode. This paper makes To solve this problem in different ways design, the problem is divided into two parts, the first part of the solution in the frequency domain model design, The second part gives the result in the time domain. The simulation results show the effectiveness of the solution.)
