空情数据融合的算法研究

Study on Fusion Algorithm Based on Air Target Information

炮瞄雷达由于波束很窄,不具备大范围搜索功能,利用其他雷达的空情共享数据,可以多渠道为炮瞄雷达提供空情数据支持。由于各雷达向炮瞄雷达传送目标数据时需要进行数据融合处理,就是将各雷达的球坐标转换为炮瞄雷达的球坐标。论文讨论了在考虑地球曲率影响下,利用GPS定位系统和WGS-84坐标系进行坐标转换,有效减小误差,满足系统的精度要求。

Due to the narrow beam,the gun-directing radar does not have wide range of automatic search function.By using the shared data from other radar,the gun-directing radar can be provided by many aspects.The data will be carried out by means of amalgamation,when the other radar transmits data to the gun-directing radar.It is to convert the spherical coordinates of a radar in?to the spherical coordinates of the gun-directing radar.An algorithm method of coordinate transformation through WGS-84 coordi?nate system in the situation of the earth's shape is discussed in the article.The method is satisfied with the system in required preci?sion.
