环境数学模型，利用椭圆法以及matlab数学环境制作的数学模型，效果还不是特别的好(прикладная задача математического моделя )

利用周期图法对序列的功率谱进行估计。数据窗采用汉明窗。假设在白噪声中分辨这三个不同频率的正弦信号,其相位是均匀分布在2PI的独立随机变量,而 是一个单位白噪声.生成50个长度为N=512的 的样本序列集合。 (use map cycle sequencing method of the power spectrum estimation. Data window using Hamming window. Assume that the white noise to differentiate between the three different frequency sinusoidal signal, its phase is uniformly distributed in the PI two independent random variables. but a flat white noise. Generating 50 length N = 512 samples of the sequence set.)

里面有关于MATLAB的基本使用的方法和定义，初学者可以好好的(There are on the basic use of MATLAB methods and definitions, can be good for beginners)

1.本程序是自己刚刚接触SAR时编写的时域星载SAR点目标回波仿真，包含了卫星轨道模型、计算星目斜距时用到的各种坐标系转换、SAR回波计算模型以及简单的SAR成像模型，希望对初学者有所帮助。 2.相应的参考资料可查找《卫星轨道姿态动力学与控制》及《魏钟铨_合成孔径雷达卫星》；(1. This program is just contact with their own prepared when the time domain SAR spaceborne SAR point target echo simulation, contains the satellite orbit model, the satellite project when the use of a variety of slant range coordinate system conversion, SAR echo calculation model and SAR imaging model simple, want to help beginners. 2. The corresponding reference can be to find " satellite attitude and orbit dynamics and control" and " Wei Zhong Quan _ synthetic aperture radar satellites" )
