In order to solve the problem that the existing test methods of infrared imaging guidance seeker’s anti-infrared decoy missile are not enough, this paper establishes a test system which is composed of three-axis turntable and rocket sled, and simulates the combat process of missile close to the target realistically. Using the sledding track conversion algorithm and the active disturbance rejection algorithm, the two technical problems of the sledding track in real time and the overshoot vibration during the start of the sledding are solved. This test system has been used in the anti-decoy missile jamming test of multi-type infrared imaging guidance seeker.
