The influence of time delay error of target simulator in infrared imaging guiding semi-physical simulation system on the confidence degree in guidance and control system was studied. According to the simulation precision of target IR characteristics, influence factors of the error of infrared target simulator were analyzed and the error compen- sation algorithm was presented. Firstly, the main error sources that influence simulation precision were analyzed based on the principle of infrared target simulation. Then, considering the generating mechanism of time delay error in infra- red CIG, the impacts of time delay error on some parameters including geometric resolution, angular resolution,lateral position of moving target, radial position of moving target were analyzed. Finally, the compensation algorithm for time delay error in IR CIG was derived. Simulating and testing results show that the proposed algorithm can better compensate time delay error of IR CIG and improve the simulation precision. The algorithm provides the foundations for system optimization design of infrared imaging guidance weapon.
