FIR-F-ilters-in-Matlab

this program simulates 1D electromagnetic Maxwell equations with absorbing boundary condition to prevent reflection from the boundaries of the problem space. this is by using finite difference time domain method FDTD

hough变换的检测函数，调试成功的，可以用，对于圆检测很有帮助，大家可以学习一下(hough transform function testing, debugging successful, you can use, very helpful for circle detection, we can learn about)

说明：  简易SSB设计 有详细的报告和说明，可以作为参考(Simple SSB detailed design reports and notes, can be used as reference)

FDTD仿真二维圆柱隐身衣，附理论推导和matlab程序 二维TM波（Hx Hy Ez），传的是TE波的程序其实道理是一样的。边界采用UPML，平面波靠总场/散射场引入(Two-dimensional TM wave (Hx Hy Ez), TE wave transmission is in fact the procedure is the same reason. Boundary using UPML, a plane wave by the total field/scattered field into )

成像处理一般包括三个步骤：1、距离向脉冲压缩，对一个合成孔径内的每个回波脉冲均进行压缩；2、距离徙动矫正，把属于同一点目标的脉冲校正到等距离线上、3、方位向脉冲压缩。(Imaging process generally comprises three steps: a distance to the pulse compression of echo pulses each have an inner aperture compression 2, range migration correction, the pulses belonging to the same point in the correction target line equidistant , 3, azimuth compression to pulse.)

说明：  加信噪声，单边带调幅，设计波特滤波器，过滤噪声，比较经过希尔伯特变换前后的区别(Plus letter noise, single-sideband amplitude modulation design Potter filters, filter noise comparison, after the difference between before and after the Hilbert transform)

simulink 采样系统的一个简单的例证，采样周期为0.1，使用了保持器(simulink sampling system, a simple example, the sampling period is 0.1, the use of retainer)

L曲线具有很多的优点，这是用MATLAB编写的病态方程的L曲线解决方法，可以通过L曲线确定所需的参数。(L curve has many advantages, it is written in MATLAB morbid equation L curve solution that will be needed through the L curve to determine the parameters.)

和自回归模型一起写的小波模型，里面用到了自回归，自回归模型已上传(Since the regression model and the wavelet model with writing, which used the autoregressive, autoregressive models have been uploaded)
