【信息处理】基于GUI数字波束的算法库含Matlab源码

1 简介

将多种数字波束形成算法融合到一个平台,不仅丰富了数字波束形成仿真平台的功能,而且还可以为用户二次开发提供便利.利用MATLAB GUI开发了包含线性约束最小方差(LCMV),最小方差无失真响应(MVDR),最大信噪比(MSNR)准则等算法的波束形成仿真平台,该设计实现了与用户交互,波束形成过程可视化,方便对波束形成算法的研究,是研究自适应波束形成的一个有力工具.

function varargout = algrithem_database(varargin)
% ALGRITHEM_DATABASE M-file for algrithem_database.fig
% ALGRITHEM_DATABASE, by itself, creates a new ALGRITHEM_DATABASE or raises the existing
% singleton*.
%
% H = ALGRITHEM_DATABASE returns the handle to a new ALGRITHEM_DATABASE or the handle to
% the existing singleton*.
%
% ALGRITHEM_DATABASE('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in ALGRITHEM_DATABASE.M with the given input arguments.
%
% ALGRITHEM_DATABASE('Property','Value',...) creates a new ALGRITHEM_DATABASE or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before algrithem_database_OpeningFunction gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to algrithem_database_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
