灰度 GM（1.1）模型：灰色系统其内部一部分信息已知，另一部分信息未知或不确定。对既含有已知信息又含有不确定信息的系统进行的预测，也就是对在一定范围内变化的、与时间序列有关的灰过程进行 预测。(Gray GM (1.1) model of grey system: the internal part of the information known, the other part of the information is unknown or uncertain. In which there are both known information and uncertain for the prediction information system, is also the process of gray change in a certain range, with the time series related to Prediction.)

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" )
