SAR_DPCA

基于matlab的图像增强技术，包括灰度变换，锐化，彩色增强和频域增强(Matlab-based image enhancement technology, including gray-scale transformation, sharpening, color enhancement and frequency domain enhancement)

An alternative to Matlab s HIST, function HISTW prevents extreme values in top and bottom percentiles of an input vector affecting the histogram s scaling, obscuring location and shape of the distribution s main mass. Limits of x and y (maximum only) axes can be set, and a marker line drawn at given x position. In contrast to HIST, bin size can be explicitly specified, and relative, rather than absolute, frequencies are plotted.

共炮点地震记录合成，添加不同比例噪声，进行小波变换去噪处理，得到比较理想的效果(the synthetic seismic record of common shot, add different noise, and do wavelet transform on it, then we can get a better record)

拨号按键识别GUI界面程序，原理采用DTMF，本程序随意按下六位数字，当按下第七位的时候屏幕清空，点击解析，结果将显示在文本框中，并有相应的声音。(GUI interface dial buttons identification procedures, principles using DTMF, this program free to press the six figures, when you press the seventh, when the screen is empty, click the analytical results will be displayed in the text box, and a corresponding sound.)

说明：  基于MATLAB实现的mie散射程序，可以计算散射消光不对称因子等参数(The Mie scattering program, based on MATLAB, can calculate the parameters of scattering efficiency, extinction efficiency, asymmetry factor, and so on)

说明：  对图像进行处理后常需要计算图像的PSNR值和NC值(calculate the PSNR and NC of pictures)

GO-CFAR检测是信号处理中非常常用的检测方法。该程序比较了理论值和实际值的仿真结果。实际中雷达信号往往是起伏的，该程序从SweringI型为例。(GO-CFAR detection is very commonly used detection methods in signal processing. The program compares the simulation results of the theoretical and actual values. The actual radar signals often are ups and downs of the program from SweringI type, for example.)
