基于Kalman滤波的飞行中对准技术研究

In-flight Alignment Technique Based on Kalman Filter

对于要求快速反应能力的导弹武器系统,初始对准难以满足武器系统对快速性的要求。这种情况下,发射平台只提供简单的初始化,对准过程在导弹飞行过程中完成,这种方法称为飞行中对准。建立了飞行中对准的数学模型,通过仿真计算研究飞行中对准的性能以及影响对准性能的因素。

To the missile weapon systems requiring rapid reaction time, initial alignment can not satisfy the weapon systems＇ requirement of reaction time. To solve this problem, the launch platform just provides a simple initialization, and the alignment process is performed during the missile＇ s flight. The method is called in-flight alignment. A mathematic model of the in-flight alignment is established, and the performance of in-flight alignment and elements affecting the performance are analyzed by simulation.
