说明：  阵列存在幅相误差条件下的DOA估计算法仿真(Simulation of DOA estimation algorithm with amplitude and phase errors in array)

说明：  粒子滤波重采样算法对比与分析，matlab实现。(Particle filter resampling algorithm comparison and analysis, matlab achieve.)

EKF,UKF,PF,EKPF四种滤波算法的比较和matlab编程，能实现简单的单个目标跟踪滤波(EKF, UKF, PF, EKPF four kinds of comparison and filtering algorithm matlab programming, to achieve a simple single target tracking filter)

完成前台阶问题的计算，利用的AUSMPW格式，算法结构较为简单，所以文字说明较少(Completed on the front steps of the calculation, use of AUSMPW format, the algorithm structure is relatively simple, so less text)

电磁场 向量分析与场论基础 《向量分析与场论基础》就是关于场的数学刻画、描述以及场特征的一般分析。在本概要中，为简明区分向量与标量起见，向量一律采用黑、斜体。 (vector analysis and electromagnetic field theory based "vector analysis and field theory foundation" is on the mathematical characterization. and the description of the general characteristics of the market analysis. In the outline for concise distinction between vector and scalar sake, vector will be used black, in italics.)
