这次是添加不同密度的高斯噪声，和上次可做对比。(This is to add Gaussian noise of different densities, and the last to do comparison.)

说明：  常规波束形成方位谱和MVDR方位谱对比，课本上的例程(Comparison of conventional beamforming azimuth spectrum and MVDR azimuth spectrum)

这是MATLAB 和 LABVIEW 混合编程方面的书籍 介绍了 MATLAB 脱离 MATLAB 环境运行。(this is a good code for that matlab to dll. welcome to download )

换能器阵元的不同排列组合决定其指向性，波束形成是多波束测量的关键技术。文中 通过数学计算总结了不同换能器阵进行波束形成的工作原理，并介绍了利用二维DFT进行频 域波束形成的一般方法。最后结合现役多波束测深系统，简单解释说明不同系统所采用的波束 形成技术。(Transducer using an array of different permutations and combinations to determine its directivity, beam formation is the key technology for multi-beam measurements. Summarized by mathematical calculations the transducer array beamforming works, and describes the general method of two-dimensional DFT in the frequency domain beam formation. Finally, the active-duty multi-beam sounding system, the simple explanation of the different systems used in beamforming technology.)
