生成一个采样频率2000，由50Hz、120Hz、200Hz正弦信号以及噪声信号组成的数字信号，滤掉150Hz>f>100Hz的频率，计算并显示滤波前后的原始数据波形以及功率谱密度。(A sampling frequency of 2000, a digital signal composed of 50Hz, 120Hz, 200Hz sine and noise signals, is generated to filter out the frequency of 150Hz>f>100Hz and to calculate and display the original data waveforms and the power spectral density before and after the filtering.)

说明：  采用FDTD计算2维光子晶体的散射和透射的可执行程序小软件，修改输入文件可用于光子晶体的建模和计算，比较好用(FDTD calculation using two-dimensional photonic crystal scattering and transmission of the executable program small piece of software, modify the input file can be used for modeling and calculation of photonic crystals, compare easy to use)

二色散射模型去雾算法，以及深度图的获取，效果较好(Dichroic scattering model to fog algorithms, as well as the acquisition of the depth map, the better)

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.)
