Mathematical Model of the Simulation System with HWIL for Infrared Imaging Homing Missile

In distributing precision of a simulation system with HWIL (hardware in the loop) for infrared imaging homing missile, it is difficult to calculate precision sensitivity of each equipment to the simulation system with HWIL. The problem has been solved in this paper by establishing simulation models of the simulation system, doing simulation experiments and statistical estimating. According to the Second Newton Law, image manipulation technique and the national standard of simulation equipment, a general method and a principle of establishing simulation models of target simulator's 2 axis rotator; missile body attitude 3 axis rotator, load simulator, over loading simulator and infrared imagining system are put forward in this paper. Without linearizing the movement model of rigid body, meanwhile, the coupling between axes of the rotator and the influence of the infrared imagining technique are fully considered, resulting a more accurate, effective and common model.
