Technologies Study and System Design of Digital Image Stabilization in Single Channel-controlled Air Defense Missile

A novel missile digital image stabilization (MDIS) approach was proposed, which settled the coupling problem in single channel-controlled air defense missile without inertia devices such as gyro. In the course of getting stabilized target images, some important real-time motion parameters of missile were estimated. The basic principle of MDIS was analyzed, and the key technologies were studied including imaging modeling of relative motion, method of missile motion estimation and method of motion compensation in images. Then an MDIS system model was designed. The simulation results show the feasibility and efficiency of this MDIS approach.
