Since active radar/IR imaging compound guidance becomes an important development direction of compound guidance, and information fusion is one of the key technologies in compound guidance, research on information fusion based on radar/IR imaging compound guidance has important values in both theory and engineering. Start from the engineering application of radar/IR imaging compound guidance, some technologies about information fusion in distributed system of radar/IR imaging compound guidance were researched, including tracking f＇dter algorithm, data preprocessing （including time registration, space registration, as well as outlier elimination of measurement data）, data association and data fusion （including detection fusion, recognition fusion and tracking fusion）. Under the condition of measurement noises correlating, a weighted track fusion algorithm was researched in theory and by digital simulation. The simulation results show that this fusion method has high precision and good real-time performance, so can meet the need of information fusion of active radar/IR imaging compound guidance.
