| 摘 要： | 利用弹体姿态解耦算法,对捷联成像导引头的目标视线角速率进行提取。针对捷联成像导引头大的瞬时视场带来的大的测量噪声,采用TD跟踪微分器进行视线角速率重构和滤波。经数学仿真验证,滤波后所得到的视线角速率信息可直接应用于比例导引控制,有效提高了制导精度。

| Abstract: | The methods of line-of-sight(LOS) and LOS rate reconstruction in the strap down imaging system are investigated based on the analysis of decoupling missile attitude from the measurement of strap down imaging seeker.Large instantaneous field of view will cause great background noise and any inaccurate metrical information used by the reconstructing system would be reflected to the final LOS,thus,the filter is required.A novel LOS reconstruction filter is proposed to obtain more precise inertial LOS informati... |
