摘要
为了实现雷达组网中的数据融合和共享,需要将目标信息统一到一个相同的坐标系下。通过获取目标的GPS信息可以统一坐标系。文中从理论与工程实践的角度,分析了机载平台下雷达常用的各个坐标系,结合它们之间的联系和特点,推导并实现了从常用的目标载机坐标到GPS坐标的转换过程。同时,文中的公式都可以直接用于工程实现,对于现代机载雷达组网、无人机平台及预警机平台中的目标预警、数据融合等都有着广泛的参考和借鉴价值。
In order to achieve data fusion and data sharing of netted radar, target information are needed to unify into the same coordinate by getting the target GPS coordinates. Gonceptions of reference frame are analysed for airborne platform from theory and practice, and the coordinate transformation is evolved and implemented from airborne spherical coordinates to GPS coordinates by combining their charac- teristics and relations. Meanwhile ,all expressions in this paper can be used in practice ,so it is great worth while using it for netted radar and data fusion for airborne platform,UAV or airborne warning aircraft platform.
