利用粒子群算法对直线阵的权系数进行优化，这里只是对相位进行加权，但是程序有很好的宽展功能(Using particle swarm algorithm of linear arrays of the weight coefficient is optimized )

线性调频信号的幅频特性，脉压处理，脉压后的带宽，峰值旁瓣比，积分旁瓣比性能的检测。(The amplitude and frequency of the chirp signal characteristics, pulse pressure processing bandwidth of the pulse pressure, peak sidelobe ratio, integral sidelobe ratio performance testing.)

说明：  这是一个快速的三维图像双边滤波的实现。这个过滤器平滑图像的同时保留边缘，但在其最直接的实现是非常计算的要求，特别是对大型3D图像。快速双边滤波是一种近似技术，极大地提高了计算速度。我的实现严格遵循Matlab版的快速二维滤波器，只是做了一些修改(This is an implementation of fast bilateral filtering for 3D images. This filter smoothes the image while preserving edges, but in its most straightforward implementation is very computationally demanding, especially with large 3D images. Fast bilateral filtering is an approximation technique which drastically improves the speed of computation. My implementation closely follows the Matlab version of the fast 2D filter with some modifications)

实现了最速下降法的算法，具体实例操作，可运行出结果，分子程序书写，简便易懂。(The algorithm of the steepest descent method, and specific examples, you can run the results, the molecular program written in easy to understand.)
