摘　　要：结合工程应用中的实际问题,模拟实船干扰因素情况,采用理论和仿真分析相结合的方法,研究了船体变形、舰船运动、基准信息跳变等对舰载武器速度匹配传递对准性能的影响。结果表明:1)速度匹配传递对准不易受船体变形影响;2)舰船航向机动有助于提高速度匹配传递对准性能,舰船在匀速直航状态下,方位姿态角对准精度2′左右,等效北向陀螺漂移的估计精度能达到80%,无法估计等效东向陀螺漂移和加速度计零偏;舰船在转弯状态下武器惯导各误差量估计精度和估计速度都有所提高,能够估计等效东向陀螺漂移和加速度计零偏,估计精度达90%以上;3)基准信息跳变会干扰速度匹配传递对准性能,引起姿态角估计误差。This paper analyzes the impacts of a variety of interference factors, including hull deformation, course maneuvers, and sudden changes of benchmark information, on the ships＇ performance in velocity matching and transfer alignment. The research stems from practical engineering problems and is based on theoretical analysis as well as simulations. The results show that （1） the performance of both velocity matching and transfer alignment is insusceptible to hull deformation; （2） the performance of the transfer alignment may be improved by course maneuvers; （3） the general performance is disturbed and the attitude estimation errors increase when benchmark information suddenly changes. Particularly, when the ship is under constant velocity, the alignment accuracy of azimuthal attitudes is approximately 2＇, the estimation accuracy of equivalent north gyro drifts is only 80%, and the equivalent east gyro drifts and accelerometer bias cannot be obtained at all. On the other hand, when the ship is under swerve motion, the estimation of onboard weapons＇ inertial navigation status is improved in terms of both accuracy and speed. In this case, the equivalent east gyro drifts and accelerometer bias can be successfully estimated whose precision reaches 90%.
