Abstract The information of radar emitter acquired by reconnaissance equipment is partial and fuzzy under complicated electromagnetic environment. For this reason, this paper firstly analyzes the characteristics of modern radar ELINT, and then identifies radar emitter by means of Dempster-Shafer fusion method based on multi-data from various kinds of reconnaissance equipment. It designs Basic Probability Assignment Function (BPAF) of emitter characters. It presents a three-degree fusion algorithm, including emitter character fusion, multiple reconnaissance period time fusion, and multiple reconnaissance equipment space fusion. The fusion algorithm is proved to have superior performance with the help of simulation results.
