An Evaluation Method of Information Fusion Capability Based on Combined Weight Method

Abstract

Information fusion technology can obtain more detailed information by synthesizing multi-source information, thereby providing information support for coordinative operations. The information fusion capability evaluation can not only analyze the performance of reconnaissance systems in a certain battlefield environment and make the decision more scientific, but also play an important role in the direction of its future research and development. This paper proposes a method for evaluating information fusion ability based on the combined weight method. It constructs an evaluation indicator system of information fusion ability from three aspects: quickness, accuracy and stabilization, and gives calculations and normalization of each indicator in detail. This paper uses analytic hierarchy process to calculate subjective weights and entropy weight method to calculate objective weights, which are combined effectively by relative entropy combination weighting method. Finally, a reasonable combination parameter value is obtained, and an example simulation of information fusion ability evaluation is completed.
