伪随机相位编码脉冲雷达的信号处理
伪随机相位编码脉冲雷达的信号处理。设码频 02，单位为 MHz，伪码周期内码长为 127，占空比 10%，雷达载频为 10GHz，输入噪声为高斯白噪声。目标模拟分单目标和双目标两种情况，目标回波输入信噪比可变（-35dB～10dB），目标速度可变（0～1000m/s），目标幅度可变（1～100），目标距离可变（0～10000m），相干积累总时宽不大于 10ms。单目标时，给出回波视频表达式；脉压和 FFT后的表达式；仿真 m序列的双值电平循环自相关函数，给出脉压后和 FFT后的输出图形；通过仿真说明脉压输出和 FFT输出的 SNR、时宽和带宽；仿真说明脉压时多卜勒敏感现象和多卜勒容限及其性能损失（脉压主瓣峰值与多卜勒的曲线）。双目标时，仿真出大目标旁瓣掩盖小目标的情况；仿真出距离分辨和速度分辨的情况。(Signal processing of pseudo-random phase coded pulse radar)

程序目的： 输入一个任意大小的迷宫，用栈求出一条走出迷宫的路径，并 显示在屏幕上。 程序实现： 可以实现载入迷宫和保存迷宫，附带文件中有4个测试迷宫路径的 文件test1~4.dd。请将这些文件拷贝到TC当前目录下，或者在载 入时写明完全路径。由于屏幕大小的限制，当用户自己输入迷宫 时一定要注意：迷宫大小是有限制的，不小于4*3,不大于30*20。 否则会出现错误信息。输入开始时全是墙，用上下左右键移动， 用Del键删除墙，形成通路，用Enter键添加墙。输入结束时可以 将迷宫保存下来，以dd为扩展名。输入完毕时用F9键来得到结果， 找到路径时，屏幕下方会出现Path found，否则出现Path not found。 程序经Turbo C 2.0编译调试成功。运行时不用添加任何运行库。 不可以在VC上编译。-procedures purpose : to bring in a maze of arbitrary size, with a stack get out of the maze of trails and on the screen. Program : can achieve and preserve the printed maze maze, the accompanying documents were four test maze of trails to document test1 4.dd. I would be grateful if those files are copied to the TC current directory, or in the state when fully contained path. Due to restrictions on the size of the screen when the user input labyrinth must pay attention to : the size of the maze is a restriction, not less than 4* 3, not more than 30* 20. Otherwise there will be a wrong message. At the beginning of the importation of a

帧差法
利用转换公式将真彩图像转换为灰度图像。将灰度图像的每一个像素点对应一个元素保存在一个矩阵中。然后利用帧差法进行图像差分处理，从而提取出运动目标。对差分后的图像二值化处理，用最大类间方差分割法遍历求取最优阈值。使其作为基准，区分差分图像的背景元素和目标元素。最后用matlab进行编程使目标信息高亮显示在屏幕上。(The true color image is converted to gray image by transformation formula. Each pixel of a grayscale image is stored in a matrix corresponding to one element. Then the frame difference method is applied to image difference processing to extract moving targets. After the two valued processing of the differential image, the optimal threshold is obtained by traversing the maximum variance between classes. It is used as a benchmark to distinguish the background and target elements of the differential image. Finally, Matlab is programmed to highlight the target information on the screen.)
