The virtual prototype technology , a digital design mothed based on computer simulation model of production, is a brand- new development technique. Virtual prototype can be used for innovative design, test and evaluation instead of physical prototype. Virtual prototype environment is supported by virtual prototyp system for the delelopment and simlulition of infrared imaging seeker, which is composed with some subsystems including electronic subsystem, mechanical subsystem, software subsystem, and control subsystem. Using virtual prototyp system, the period of development of infrared imaging seeker can be shortened, while the cost and venture can be reduced. In this paper, the architecture, function and elements of virtual prototyp system for infrared imaging seeker are presented, and the course of development of infrared imaging seeker based on virtual prototype is also introduced.
