分析了大地直角坐标系和舰船直角坐标系的关系,在舰船直角坐标系中对舰载雷达三轴转台系统的姿态角进行了定义,用空间解析几何法推导出已知舰船平台罗经信号、天线姿态角时三轴转台系统的稳定方程,为舰载雷达三轴转台系统的伺服控制提供理论依据。

The relationship between geodetic coordinate system and ship coordinate system is analyzed, the three-shaft-stabilized system’s attitude angles of the ship-borne radar in ship coordinate system are defined, when the value of platform compass and the ship-borne radar antenna’s attitude angles are given. A way to the three-shaft-stabilized system’s steady-state equations is provided by use of space analytic geometry method, which provides a theoretical basis for the serve control of the three-shaft-stabilized platform.
