Abstract: The design and research of an advanced infrared-imaging homing head simulator were introduced, and its architecture,major performance parameter,track arithmetic and experiment results were provided. Based on succeed designedimaging identify and track circuit which contain two parallel microcomputers, corresponding different ground goals, developed different track arithmetic and noise generated arithmetic program. The system can simulate manifold homing head. It could be installed in the helicopter to search, capture and trace multi-objectives, to verify the fact of bad climate, smog and changing space resolution that will effect imaging identify and track. It can also make many interfere experiments to verify interfere effect. The results of experiments show that the system can achieve expected application effects. These tests offer a great deal of originality materials for simulated experiment, also provide important data to design and use infrared-imaging homing system.
