ISAR运动补偿逆合成孔径雷达运动补偿逆合成孔径雷达(ISAR motion compensation ISAR motion compensation inverse synthetic aperture radar)

利用广义相关法求时间延迟估计，可以用用在TDOA定位中(Generalized Correlation Method Using Time Delay Estimation)

说明：  一个ga的matlab源程序，读懂它可以方便地处理问题。(ga matlab procedure，read it you can deal with your problem easily)

哈米尔顿回路！！！经典的ACO_Hamilton！！！图论必用(Hamilton circuit! ! ! Classic ACO_Hamilton! ! ! Graph theory must be used)

小波矩的matlab代码，主要用于全局特征提取使用，比较简便(Wavelet Moment matlab code, mainly for global feature extraction using relatively simple)

mathews数值分析书的源代码，用matlab编写，第一章第十一部分。(mathews numerical analysis of the book' s source code, using matlab, the first chapter of Part XI.)

利用各待评方案的指标体系，通过计算各待评价方案与理想解的接近程度，作为评价各方案的依 据的一种多目标决策评价方法(topsis sort)

使用卡尔曼滤波器设计的运动物体跟踪。适用于背景也是动态变化的物体跟踪(Tracking moving objects using a Kalman filter design. Applies to the background also dynamic object tracking)

可以完成地震记录的合成，实现地震记录的正演模拟(Synthetic seismogram can be done to achieve forward modeling of seismic records)

当信噪比低，小信号输入时噪音严重，在整个音域的声音明显变得浑浊不清，不知发的是什么音，严重影响音质。信噪比的大小是用有用信号功率（或电压）和噪声功率（或电压）比值的对数来表示的。(When the signal to noise ratio is low, serious small signal input noise, the sound of the entire range becomes significantly turbid, I do not know what made the sound, seriously affecting the sound quality. Size is the number of the signal to noise ratio by the ratio of desired signal power (or voltage) and the noise power (or voltage) represented.)
