合成地震记录是用声波测井或垂直地震剖面资料经过人工合成转换成的地震记录（地震道） 合成记录的制作是一个简化的一维正演的过程，合成记录F(t)是地震子波S(t)与反射系数R(t)褶积的结果。(Synthetic seismogram is sonic or vertical seismic profile data after conversion into synthetic seismograms (seismic trace) the production of synthetic seismogram is a simplified one-dimensional forward modeling process, synthetic seismogram F (t) is the seismic wavelet S (t) and the reflection coefficient R (t) the convolution results.)

图1为均衡带限信号所引起失真的横向或格型自适应均衡器(其中横向FIR系统长M=11), 系统输入是取值为±1的随机序列，其均值为零；参考信号；信道具有脉冲响应： 式中用来控制信道的幅度失真(W = 2～4, 如取W = 2.9,3.1,3.3,3.5等)，且信道受到均值为零、方差(相当于信噪比为30dB)的高斯白噪声的干扰。试比较基于下列几种算法的自适应均衡器在不同信道失真、不同噪声干扰下的收敛情况(对应于每一种情况,在同一坐标下画出其学习曲线): 1）横向/格-梯型结构LMS算法 2）横向/格-梯型结构RLS算法 并分析其结果。(Figure 1 is a band-limited signal caused balanced horizontal or lattice distortion adaptive equalizer (FIR system in which the lateral length M = 11), the system input is the value of a random sequence of ± 1, mean zero reference signal channel has impulse response: Wherein the amplitude of the distortion for the control channel (W = 2 ~ 4, and so as to take W = 2.9,3.1,3.3,3.5), and subjected to a channel with zero mean and variance (equivalent SNR is 30dB) Gaussian white noise. Compare the following types of algorithm-based adaptive equalizer in a different channel distortion, the convergence of different noise interference (corresponding to each situation, draw their learning curve in the same coordinate): 1) landscape/grid- LMS algorithm ladder structure 2) landscape/grid- RLS algorithm ladder structure And analyze the results.)

这是一篇硕士论文,题目是多目标优化的遗传算法研究(This is a master' s thesis topic is a multi-objective optimization by genetic algorithm)

这是关于matcom和C++联合编程的资料，可以实现脱离matlab环境来进行编程(This is joint programming on matcom and C++, the data can be achieved out of the matlab environment for programming)

设雷达信号是码宽为0.5微妙，中心频率是10MHz的7为巴克码2PSK信号，接收的雷达回波中频采样频率为为40MHz，中频进行正交下变频。假设在13.5km处有一个点目标，仿真该雷达的脉冲压缩处理。 已通过测试。 (Let the radar signal is yards wide 0.5-subtle, the center frequency of the the Buck the code 2PSK signal, the received radar echo IF sampling frequency of 10MHz to 40MHz, IF quadrature down-conversion. Assuming the 13.5km at a point target simulation of the radar pulse compression processing. Has been tested.)

自动叠加，很好用的，哈哈，费了老大的劲搞的啊！！！！！(Automatic stacking )

说明：  基于matlab简单图像处理系统中对图片的取反功能(Based on a simple matlab image processing system for the inversion of the image)
