现需要在高度为600~700KM范围内，回归周期为30天的太阳同步轨道上布置一颗L波段的合成孔径雷达卫星。 1. 请设计合适的轨道参数，并仿真对应轨道下一个运行周期内星下点轨迹图（纬度和经度两个图）； 2. 计算多普勒中心频率，多普勒调频率与纬度的关系图（设姿态角为0°，天线视角20°~60°，推荐35°）； 3. 按高斯投影方式，将星下点轨迹图投影到地图坐标上。(Now requires a height of 600 ~ 700KM range, return period of 30 days are arranged on a sun-synchronous orbit L-band Synthetic Aperture Radar satellites. 1 Please design the appropriate orbital parameters and simulate the corresponding orbit within the next operating cycle nadir trajectories (latitude and longitude two graphs) 2. Calculate the Doppler center frequency, Doppler frequency and the relationship between latitude Figure (set attitude angle is 0, the antenna angle of 20 to 60, recommended 35) 3 Press Gauss projection, the nadir trajectories projected onto the map coordinates.)

相图与庞加莱截面，但程序有点问题，需要交流，相图应该是对的(A problem, the phase diagram and Poincare section)

使用非线性支撑矢量机对一组数据进行分类。画出分界面(The use of non-linear support vector machine classification on a set of data. To draw the interface)

角点是图像的重要特征，一般指曲率大的边缘点，该代大戏是用MATLAB编写的角点检测算子。(corner image is an important characteristic of large curvature generally refers to the brink, The show is substituting prepared using MATLAB corner detection operator.)

一个可以提取图像轮廓的小程序，简单易懂，效果不是太好(An image contour can be extracted a small program, easy to understand, the effect is not too good)
