潜射导弹捷联惯导系统传递对准技术研究

随着现代战争的发展,潜射导弹已成为日益重要的中等规模打击力量,快速而准确地在潜艇上对其捷联惯导系统进行传递对准,成为潜射导弹的一项关键技术。该文通过研究主、子惯导之间产生的固定安装误差角和挠曲变形角,运用鲁棒滤波技术,采用＂角速度＋加速度＂匹配的传递对准方法进行了建模和仿真。结果表明,该技术可以实现潜射导弹捷联惯导系统的快速高精度对准,而潜艇不必做其他机动,为导弹快速高精度初始对准提供了一定的理论依据。

Transfer Alignment Techniques of Strapdown Inertial Navigation System for Sub-launched Missile

With the development of modern wars,sub-launched missile has played an important role in medium-scale attacks.So fast and accurate transfer alignment of strapdown inertial navigation system（SINS） on moving submarine becomes a crucial technique.We investigate the misalignment angle and the uncertain angle between master inertial navigation system（MINS） and strapdown inertial navigation system（SINS） making use of H∞ filter method,then model and simulate the design of the transfer alignment based on angular rate and acceleration matching.Simulation results show that with our method the higher precision and shorter response time for the transfer alignment of sub-launched missile are obtained without needing submarine for any other maneuvering.
