摘要
为克服噪声干扰,实现高精度飞行器激光制导,提高导弹击中精度,提出基于反馈跟踪滤波检测的飞行器激光制导方法。该方法使用反馈线性化技术,从纵向制导、侧向制导两种角度设定制导律,飞行器可遵循制导律的设定,跟踪目标位置,发射导弹打击目标;为了克服制导过程中存在噪声干扰,设计基于毫米波/红外复合制导的跟踪滤波方法,按照跟踪目标机动信息,设定合理滤波增益,实时调节滤波,完成高精度跟踪目标定位。实验结果验证:这种滤波技术能够提升飞行器激光制导精度;保证导弹击中目标呈直线击中状态,击中精度显著,且制导信号首尾呼应,可提升飞行器运行稳定性。
We proposes a laser guidance method based on feedback tracking filter detection to overcome the noise interference,realize the laser guidance of high precision aircraft and improve the hit precision of missile.We use the feedback linearization method,and the customized guidance law is set from the two aspects of longitudinal guidance and lateral guidance.The aircraft can follow the guidance law,track the target position and launch the missile to attack the target.Consider the noise interference in the guidance process,the tracking filtering method based on millimetre wave/infrared composite guidance is adopted,and the reasonable filtering gain is set according to the target manoeuvre information.Then,the filtering equation is adjusted to achieve high-precision target tracking.The experimental results show that the proposed method can improve the laser guidance accuracy of the aircraft;under the guidance of this method,the missile hit the target in a straight line,the hit accuracy is significant,and the guidance signal echoes head and tail,which can improve the operational stability of the aircraft.
