Abstract: Target photoelectric tracking systems are widely used in aeronautic，astronautic and martial projects.Digital simulation can be used to measure tracking precise，which has advantages of easier debugging，less cost and irrelative to weather.With help of computational graphic technology，foundation of scene including optical characteristics of target，effects of tracking axis and photoelectric sensor is an effective way of theoretic study about tracking system.The paper discusses a method of finding a simulating scene for sensor，which can demonstrate target’s size and gesture change in random trail.Based on the simulation software，some simple discusses about tracking and identification problem are proposed.

Key words: OpenGL, sensor, target tracking system, tracking and identification
