这是关于七参数转换的代码，他的转换精度高，另外附有原始数据(Seven parameter transformation)

类似J2000的ECI坐标系转换到类似wgs84的ECEF坐标系,方便大家应用(Convert ECI (CIS, Epoch J2000.0) Coordinates to WGS 84 (CTS, ECEF) Coordinates. This function has been vectorized for speed. Example Function Call: >> [r_ECEF v_ECEF a_ECEF] = ECItoECEF(JD,r_ECI,v_ECI,a_ECI); Where: JD is the Julian Date vector [1 x N] (units are in days) r_ECI is the position vector [3 x N] (any units are permitted) v_ECI is the velocity vector [3 x N] (any units are permitted) a_ECI is the acceleration vector [3 x N] (any units are permitted))

it was difficult to do it

说明：  聚类分析是一种模型分析，将具有相似功能的类别进行分类(Cluster analysis is a kind of model analysis, which classifies the categories with similar functions)

高频地波雷达对于天基海杂波的仿真，其中有一阶海杂波和二阶海杂波的仿真，对初学者很有帮助(HF ground wave radar clutter simulation for the DMH days, including a first-order sea clutter and second-order sea clutter simulation, very useful for beginners)
