An Efficient Estimation Method of Line-of-Sight Rate in High Maneuvering BTT Missiles

고기동 BTT미사일을 위한 효과적인 시선변화율 추정 방법

This paper describes a new LOS(Line-of-Sight) estimator for BTT missiles. The dynamic models of LOS rate and a seeker are derived. Based on these dynamic models, we design a nonlinear estimator, which takes into account roll motion of BTT missiles and sensor noises. Simulation results show that the LOS rate estimates of the proposed estimator are more accurate than those of the conventional estimator.
