摘　　要：就舰体摇摆运动对雷达的影响 ,介绍了解决问题的途径。比较了两轴稳定和四轴稳定以及两轴稳定中前馈技术和后馈技术的优缺点 ,分析了两轴稳定中前馈稳定的基本原理。介绍了平台罗经和捷联垂直参考基准两种舰体摇摆信息源。分别讨论了平台罗经和捷联垂直参考基准提供摇摆数据时前馈稳定的实现方法。在舰体摇摆信息源无速度量输出时给出了利用摇摆位置量解算摇摆速度量的公式。为解决数据传输延迟造成的数据误差 ,提出了一种数据外推平滑方法。上述原理和计算公式均经过工程实际应用检验 。This paper introduces some methods to reduce the influence in radar that caused by rock of warship. Compared two-axes stabilize and four-axes stabilize, the goodness of feedforward and feedback between two axes are show up. Analysis the basically theory of feedforward in stable the two-axes. Introduce two kinds of rock sources that refer to gyrocompass and strap-down inertial system. Discuss the methods to provide rock data of feedforward of gyrocompass and strap-down inertial system. During the output of source in non-velocity it giving a formula that use warship location tell the velocity of the rock . Provide a kind of data estimate and filter methods to solve the data error during the delay of data transplantation. The theory and the formula are all tested by actual practice .It is also valuable to solves such kind of problems.
