Antenna code for finding 3D impulse response

说明：  This is code to simulation of AM, FM, PSK, QAM modulation

this is the programs for robert prewwitt sobel operators for images from gonazalvez book digital image processing

本程序是matlab编程，采用了N-R算法中的极坐标法(This program is matlab programming, NR algorithm using polar coordinates)

电子通信系统的建模与仿真 第9章 天线及智能天线仿真 9.1 全向天线的波束下倾 9.2 天线阵的波达方向估计 9.3 天线阵的波束形成?(Electronic communications system modeling and simulation of Chapter 9 of the antenna and smart antenna simulation 9.1 omnidirectional antenna beam antenna array under the dump 9.2 Direction of Arrival Estimation 9.3 Antenna Array Beamforming ?)

matlab数字幅度调制误码率 误符号率仿真(SER AND BER SIMULATION OF PAM )

采用G-P算法用于计算混沌分析中的关联维，并有图形输出(Correlation Dimension)

这个程序包里面包含读取遥感影像的IDL代码，可以读取多个波段，并且显示图像！(This package which contains the IDL remote sensing image to read the code, which can be read by a number of bands, and display images!)

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.)
