GUI界面，对于灰度图像做简单处理，如平滑、锐化、裁剪、旋转、放大、缩小等。(image processing，include several functions)

空气中声传播的fdtd例程，简单可用，希望对大家有帮助(Fdtd airborne sound propagation routines, simply available, we hope to help)

1、 生成多周期线性调频信号，并对其进行频谱分析； 2、 对仿真生成的信号利用两种窗口函数进行STFT变换生成时频分析图(1, to generate multi-cycle chirp signal, and its spectrum analysis 2, the signal generated by the simulation window function using two STFT transform to generate time-frequency analysis chart)

关于导航定位中的卡尔曼滤波程序。X1，X2分别代表经过转换以后的位置X,Y轴的坐标。V1，V2为其相对应的速度。卡尔曼滤波可以使定位数据更加平滑。(Calman filtering program in navigation and positioning. X1, X2, respectively, after conversion to the position of the X, Y axis coordinates. V2, V1 for its relative speed. Calman filter can make the positioning data more smooth.)
