Space time mapping project of inject simulation for infrared warning and tracking device

Spatial coordinate system,battle time,simulation time and logical time in both actual battle region and simulation region was defined with regard to the space time mapping issue of inject simulation for infrared reconnaissance and warning device combined with infrared capturing and tracking device. Then mapping relationship of aerial target location in the dynamic war situation was setup according to the bridge function of station coordinate system in actual battle region and encoder coordinate system in simulation region for infrared warning and tracking device. Time mapping relationship was also established based on the bridge function of battle time and logical time. Finally,orientation,directional and postural error simulation and superior information simulation method of infrared warning and tracking device was proposed,and analysis of the above technique laid the foundation of solution of space time consistency in inject simulation test,and the space time mapping project was firstly used and validated in the testing of multi-target processing capability for infrared capturing and tracking device,which provides a foundation for forming the capability of the digital image injection simulation test for the IR capturing and tracking device.
