舰载武器惯导系统对准综述

Review on Alignment of Ship-launched Weapon INS

按照船上对准和飞行对准两条线路,概述了国内外舰载武器INS对准发展现状。分析和归纳了舰载武器INS船上对准所涉及的重要因素如测量匹配方法、机动方式、惯性传感器件误差、船体挠曲变形、杆臂效应及数据延时等,介绍了飞行对准中GPS、雷达辅助INS的模式和GPS/INS组合抗干扰技术,着重强调了影响舰载武器INS对准性能提高的主要因素并给出了解决这些问题的基本思路。最后,初步讨论了舰载武器INS对准研究发展趋势。

According to shipboard and in-flight alignment schemes, the researches on INS alignment of ship-launched weapon are reviewed. The important elements related to shipboard alignment are analyzed and summarized, such as inertial measurement matching, maneuver, inertial sensor errors, ship flexure, lever-arm and data delay. The GPS and Radar aided INS modes in-flight as well as the anti-jam technique of GPS/INS integration are introduced. The problems in improving its alignment performance are addressed and basic ideas to deal with the issues are presented. Finally, the trend of the alignment of ship-launched weapon INS is briefly discussed.
