On a new threat assessment method in information fusion processing

Aiming at the problem of threat assessment in information fusion, based on the mathematical model of target threat factors, this paper presents a new combination weighting method to determine the threat factors´ weight. According to the combined weight, TOPSIS was used to process multi-target threat assessment and threat sequencing ultimately in air-to-air combat. Finally, an example is given, showing that the method is effective and viable, and the result of threat sequencing will be more reliable.
