| 摘 要： | 舰载雷达两轴转台系统机械结构简单,可对雷达天线法线的姿态角进行控制以保证雷达波束指向,但在舰船发生摇摆时,雷达波束绕天线法线发生旋转.本文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两轴转台系统的姿态角进行定义,用空间解析几何法推导出已知舰船平台罗经信号、天线法线姿态角时两轴转台系统的稳定方程和波束旋转角方程,为舰载雷达两轴转台系统的伺服控制和波束相关补偿提供理论依据.

| Abstract: | The mechanical structure for the two-shaft-stabilized platform of the ship-borne radar is simple, which keep the direction of radar beam by controlling the attitude angles of the antenna normal, but the radar beam rotates around the an-tenna normal when ship swung. The relationship between geodetic coordinate system and ship coordinate system is analyzed, the two -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 normal's attitude angles are given, this paper provides a way to the two-shaft -stabilized system's steady-state equations and the radar beam's rotation angle equation by use of space analyt-ic geometry method, which provides a theoretical basis for the ship-borne radar serve control and correlative compensation method. |
