Research on Attitude Pursuit Guidance Law for Strapdown Homing System

This paper comprehensively analyzes the attitude pursuit guidance law which is one of the simple guidance methods for strapdown homing guidance system. Via the analytical solution of attitude pursuit, limitations on the velocities of missile and target are presented. The influence of damping, lagging and transfer parameter from rudder deviation to angle of attack on the attitude pursuit guidance law is discussed by using Automatic Control Theory. It is concluded that the velocities of missile and target should not be too large, and the stable loop of missile body should have some damping when the missile guidance system has inherent lagging, and the transfer parameter mentioned above should not be too large when the attitude pursuit guidance law is used.
