线性调频信号（LFM）是雷达信号处理中的常见信号形式。 雷达成像中通过距离和方位2个方向的脉冲压缩实现高分辨成像。 附件中对这一技术的实现和误差分析进行了MATLAB仿真。(LFM (LFM) radar signal processing is a common signal format. Radar imaging distance and direction through the direction of two pulse compression to achieve high-resolution imaging. Annex to the realization of this technology and error analysis of MATLAB simulation carried out.)

这是一些基本的matlab的图像处理源码，经过编译通过，完全可以运行，非常好用(This is some basic image processing matlab source, after the compiler is passed, can run, very easy to use)

用matlab实现ASCII和二进制码的互换，在matlab输入ASCII码字符或字符串即可，源文件里有详细的使用说明，一共有5个文件。(Matlab by ASCII and binary code to achieve the exchange, enter the ASCII code in matlab character or string can be, the source file, there are detailed instructions, a total of five documents.)

说明：  二相相移键控（BPSK）是用二进制基带信号（0、1）对载波进行二相调制。BPSK是最简单的PSK形式，相移大小为 180°，又可称为2-PSK。在群点聚集的地方，其实都不是非常有关系，在该图像中，群点分布在水平轴上的0°和180°上。由于BPSK使用严重的失真致使解调器作出错误的判断，所以该调制方式是所有PSK中最强的。但它只能以1bit/symbol调制而不适合高数据率应用情况。 (bpsk modulation)

参数可控的分数阶傅里叶变换，可通过改变参数来进行傅里叶变换(Parameters controllable fractional Fourier transform, by changing the parameters to the Fourier transform)

在同温度和和照度下，n改变时，光生电流不变。(when the temperature and irradiation are the same the output photocurrent Iph of the same piece of solar cell remains constant although the diode quality factors and reverse saturation currents are different.)

对图像中的粒子的近似圆形的衍射光斑通过高斯拟合寻找粒子的实际位置(The image of the particles through the approximately circular Gaussian fitting of the diffraction spot to find the actual location of particle)

主要实现的是2*2用户，采用qpsk调制，实现仿真模拟图(The main achievement of 2* 2 users, qpsk modulation, simulation Figure)

高阶统计量目前应用越来越广泛，它比现在的一般统计量更能反应信号的特征，具有很好的应用前景。(Order statistics used widely at present, it is the general statistics than it is now more characteristic response signals, with good prospects.)
