An analysis is made to the basic links that have effect on the resolution of the electro-optical reconnaissance system, and a method for establishing general performance predicting model is presented.With the Minimum Resolvable Temperature Difference (MRTD) as the ultimate evaluation index, the model for calculating the resolution of IR electro-optical reconnaissance system is constructed. A specific example is used for numerical simulation, which verifies the applicability of this model.
