摘　　要：针对捷联惯导系统的传递对准问题,提出了一种更精确的带有杆臂补偿和速度差乘积项的速度加姿态匹配的传递对准模型。对准模型中增加杆臂补偿项提高了系统的稳态精度;增加速度差乘积项改善了系统的动态响应,加快了滤波器收敛速度。采用"摇摆机动"的飞行轨迹,对传递对准滤波器进行了仿真;仿真结果证明了传递对准模型的有效性。A more accurate velocity plus attitude matching transfer alignment model with a lever-arm compensation term and a delta velocity product term is treated in detail. The lever-arm compensation term is added to improve the steady state accuracy of transfer alignment, while the delta velocity product term is adopted to improve the dynamic response and the convergence speed of the transfer alignment. A ‘swing moving＇ trajectory is used in the simulation of the algorithm, and the comparative simulation of the model shows that the model is more effective than others.
