Modulation

This File calculate spectral correlation function of cyclostationary signal based on frequency smoothing.

这段代码主要是实现二阶高斯低通滤波器，本段代码全部用MATLAB语言实现的。(This code is to achieve second-order Gaussian low-pass filter, the above code to achieve the full use of the MATLAB language.)

reconstruct image with an input image with interference fringe (use fft2, ifft2, angle)

DMCmatlab实现，方法有效，有详细说明，欢迎分享。(DMCmatlab realization, the method is effective, and have the detailed instructions, welcome to share. )

说明：  逆合成孔径雷达仿真舰船图像，包括舰船的俯仰、滚动、偏航运动。(Inverse synthetic aperture radar image simulation of ship, including the ship' s pitch, roll, yaw movement.)

说明：  包括细胞边缘检测，癌细胞形态学分析，癌细胞颜色分析三个例程。(Including cell detection, cell morphology analysis, color analysis of cancer three routines.)

he modeling equation of this system is MD2X+bDX+kX = F The transfer function between the displacement X(s) and the input F(s) then becomes X(s) / F(s) = 1 / (Ms2 + bs +k)
