粒子群优化算法(PSO)是一种进化计算技术(evolutionary computation)，有Eberhart博士和kennedy博士发明。源于对鸟群捕食的行为研究 PSO同遗传算法类似，是一种基于叠代的优化工具。系统初始化为一组随机解，通过叠代搜寻最优值。但是并没有遗传算法用的交叉(crossover)以及变异(mutation)。而是粒子在解空间追随最优的粒子进行搜索。详细的步骤以后的章节介绍 同遗传算法比较，PSO的优势在于简单容易实现并且没有许多参数需要调整。目前已广泛应用于函数优化，神经网络训练，模糊系统控制以及其他遗传算法的应用领域(Particle Swarm Optimization (PSO) is an evolutionary computation technique (evolutionary computation), has Dr. Eberhart and Dr. kennedy invention. Deriving from the behavior of birds of prey PSO with genetic algorithm is similar to an iterative optimization-based tools. System initialization for a group of random solutions, through the iterative search for optimal values. But there is no cross-genetic algorithm used (crossover) and mutation (mutation). But the particles in the solution space of the particles to follow the optimal search. In detail the steps after the introduction sections compared with the genetic algorithm, PSO has the advantage of being simple and easy and did not realize many of the parameters need to be adjusted. Has been widely applied to function optimization, neural network training, fuzzy system control, as well as other genetic algorithm applications)

针对稀疏圆阵的波达方向估计问题，提出了解相干求根MUSIC算法（Sparse UCA Decorrelation Root-MUSIC，SDR）。通过改进传统的波束变换方法，进行相位校正，并在波束域进行误差补偿，得到具有共轭对称结构的波束域导向矢量。在波束域进行前后向平均处理和使用求根MUSIC算法(In order to solve the direction of arrival estimation of sparse circular arrays, a new understanding of the Sparse UCA Decorrelation Root-MUSIC (SDR) algorithm is proposed. By improving the traditional beam transform method, phase correction, and error compensation in the beam domain, a beam-domain steering vector with a conjugate symmetry structure is obtained. Averaging forward and backward in the beam domain and using the root-finding MUSIC algorithm)
