为解决船体姿态的变化对天线视轴的影响问题，采用陀螺检测和前馈补偿的方法。该系统利用3个陀螺检测船摇量在三维空间的分量的方法，生成对天线3个视轴的船摇扰动的附加角速度，加入天线控制系统的速度环输入进行补偿，消除其对天线跟踪的影响。工程使用结果表明，实测隔离度指标达到46.4 dB，跟踪精度达到0.031°，与传统方法相比有效解决了船摇引起的抗扰动问题。
- Abstract:
- This paper solved the problems of the disturbed affection of the ship pose to the antenna axises by the Gyro-Detect and Feed Forward Control method. Three gyrocompasses detecting the three dimensional vectors of the ship swing were made. The additional velocities of three axises were measured，and its were added to the velocity-loop input. Decreasing the tracking affection. The results indicated that the measured isolation was 46.4dB， tracking precision was 0.031°. A comparison with the traditional projects shows that this is superior to solve the problems of the ship swing.
