Research on Line-of-Sight Rate Extraction of Strapdown Seeker
The strapdown guidance technology,which can improve the system reliability and reduce cost efficiently,has been paid great attention and developed quickly.However,the detecting information of strapdown seeker can’t be used to proportional navigation directly because it is coupled with missile attitude,so the method of Line-of-Sight (LOS) rate extraction for strapdown seeker is investigated.Background noise and any inaccurate metrical information would be reflected to the extraction result,thus a LOS rate extraction method based on nonlinear Tracking-Differentiator(TD) and unscented Kalman filter (UKF) was proposed to obtain more precise guidance information.At the last,Monte Carlo simulations are performed; the results verify the performance and effectiveness of the designed method.
