摘要
随着极区经济利益和战略意义日益凸显,空空导弹在极区作战的需求逐渐清晰。分析了捷联惯导系统指北导航算法极区工作时存在的计算溢出问题,提出了一种适应于空空导弹捷联惯导系统的基于惯性凝固格网坐标系的导航算法和传递对准算法,并设计了载机火控系统极区导航算法。数学仿真结果表明,经过载机的摇翼机动,该算法能使空空导弹捷联惯导系统的对准误差快速降低到4'以下,可以实现极区导航。
With the increase of economic benefit and strategic significance, the application require- ments of air-to-air missile in polar regions is gradually presented. The computation overflow problem of SINS north-pointed navigation algorithm is studied. A new navigation and transfer alignment algorithm based on inertial-freezing grid reference frame is presented, which is suitable for air-to-air missile polar navigation, and the fire control system is designed. The simulation results illustrates that the transfer a- lignment precision of air-to-air missile SINS is within 4＇ by wing-rock maneuver, the algorithm can meet the polar navigation requirement.
