智能控制编程及其在matlab中如何应用实现(Intelligent control programming and its implementation in matlab how to apply)

波达方向（Direction Of Arrival）估计，又称为谱估计（spectral estimation）、波达角（Angle Of Arrival）估计。一个信源有很多可能的传播路径和到达角。如果几个发射机同时工作，每个信源在接收机处形成潜在的多径分量。因此，接收天线能估计出这些到达角就显得很重要，目的是破译出哪个发射机在工作以及发射机所处的可能位置。通过测量辐射信号的波达方向（DOA全称Direction Of Arrival）或波达角（AOA）来估测辐射源的位置。理论上这种估计只需要两个接收阵元就可以确定辐射源的位置，但在实际中，由于受到角度分辨率、多径和噪声限制，所需阵元通常要多于两个。DOA定位技术原理是利用接收机处的阵列天线和波达方向（DOA）估计技术来确定一个从接收机到信源的波达方向线，即为方向线（LOB），最后利用多个接收机估计的DOA进行三角测量，方向线的交点就是信源的估计位置。(DOA (Direction Of Arrival) estimation , also known as spectral estimation (spectral estimation), angle of arrival (Angle Of Arrival) estimation. There are many possible sources a propagation path and the angle of arrival . If several transmitters simultaneously, a potential source for each multipath component at the receiver. Therefore, the receiving antenna can estimate the angle of arrival becomes very important, which aims to decipher the location of the transmitter at work as well as possible in which the transmitter . By measuring the radiation signal DOA (DOA stands for Direction Of Arrival) or the angle of arrival (AOA) to estimate the location of the radiation source . Theoretically this estimate requires only two receiving array element can determine the position of the radiation source , but in practice , due to the angular resolution , multipath and noise limits , usually required more than two array elements . DOA positioning technology is the use of an array of antennas at)

说明：  在各行各业的工程实践中，有大量的科学计算工作需要完成。传统的计算方式一般需要较长的周期，相比之下开发效率极高的MATLAB是一个更好的选择。在MATLAB中，编程细节被简化，繁琐的实现过程也被略去，用户可以将更多精力集中于所需要处理的核心问题上。 MATLAB科学计算涉及数学、机械、电子、控制和金融等多个领域。本书以MATLAB科学工程计算为立足点，介绍MATLAB在科学计算领域中如何运用庞大的科学函数库来解决一些实际问题。在函数的选择上兼顾各函数的使用频率和专业性，力求典型全面。本书可作为MATLAB课程的教学用书或者线性代数、概率统计等课程的教学辅助书。(In the engineering practice of all walks of life, there is a lot of scientific calculation work to be completed. The traditional calculation method generally needs a long period, in contrast, the development of highly efficient MATLAB is a better choice. In MATLAB, the programming details are simplified, and the tedious implementation process is also omitted. Users can focus more on the core issues they need to deal with.)
