增加船载雷达位置环船摇隔离度方法研究

Research on position loop to increase the isolation of boat rocking for shipborne radar

本文结合现有测量船自跟踪环船摇隔离技术,提出在大地手控位置环叠加反馈陀螺及前馈陀螺来增加位置环大地手控工作方式船摇隔离度的新方法,并对以上方法进行了理论分析及试验验证。通过分析及试验验证,增加陀螺后位置环大地手控工作方式船摇隔离度有明显提高,大大降低了窄波束船载雷达目标捕获难度。

In this paper, based on existing shipborne radar tracking loop isolating ship shake technology , we propose a new method that increase the feedback gyro and feedforward gyro in the manual model of the earth coordinate system to improve the ability of isolating ship shake. For the above method , we conducted theoretical analysis and experimental verification . Through analysis and experimental verification , we found after increasing the gyro loop the ability of isolating ship shake has significantly improved . These will greatly reducing the difficulty of narrow beam shipborne radar capuring target.
