【摘要】 从讨论波束形成方法在声系统中的主要作用和主要形成过程入手,介绍几种具体实现波束形成的算法。主要讨论一种能够降低硬件要求的波束形成算法——正交波束形成算法。此种方法不但适用于声系统,对于其他检测系统也有一定的实际意义。给出几种主要波束形成算法的Matlab仿真实现程序,将按照此类方法仿真所得到的波束形成指向性图与理论指向性图比较,两者非常类似。更多还原

【Abstract】 Proceeding with a discussion on the main function and formation process of the beam formation method, the reatization of some algorithms of beamforming is introduced. Among them, orthogonal beam formation method is more useful than others. This method can reduce the request for hardware. Besides being used in the audio systems, this method also can be used in many other systems. In the paper, we can see the result of simulation of Matlab. It is more similar with the theoretic result.更多还原
