Application of Tracking-Differentiator in Angular Measurements on Spinning Projectiles Using Magnetic Sensors

In this paper, the method of twin-channel tracking-differentiator (TD) has been proposed, which province roll and rate of roll for guidance ammunition by angular measurements using magnetic sensors with noise. Through simulation analysis and Compared with other methods, the efficiency and practicality of this method has been verified. The method keeps all the advantage of TD at the same time. Adjusting parameters of the algorithms is easier and easily applied to engineering.
