一种基于卡尔曼滤波的修正比例导引率

为分析雷达主动导引头抗干扰性能,建立所需数学模型,对导引头导引精度进行仿真分析。在模拟导引头进行导引所需的距离、速度以及角度信息的干扰噪声情况下,仿真分析了导引头在噪声干扰下的弹道轨迹和导引精度;为进一步提高导引头抗干扰性能,提出基于卡尔曼滤波的修正比例导引率。仿真结果证明此导引率提高了导弹的飞行稳定度和命中率,提高了导引头的抗干扰性能,为导引头试验提供理论支持和相应的试验依据。

A Terminal Guidance Law Based on Kalman Filtering

The simulation and analysis of seeker guidance accuracy is based on establishing required mathematical model for testing anti-jamming ability of the active seeker.In the context of simulating required noise of distance velocity and angle to the active seeker,the simulation and analysis of ballistic trajectory and guidance accuracy of noise jamming is done.For improving anti-jamming ability more,putting forward terminal guidance law based on Kalman filtering.The result of simulation proves that the guidance law improves the flight stability and hitting probability of missiles and anti-jamming ability,the result of this paper offers theory support and corresponding test basis.
