Comprehensive target identification method based on uncertain reasoning

Abstract

The invention discloses a comprehensive target identification method based on uncertain reasoning. Various reconnaissance equipment and methods are adopted for scouting a same target so as to obtain target information and accomplish multielement information association, and the information on properties and types sent by each information source is fused and calculated by DS (data set) evidences based on the uncertain reasoning principle, thereby obtaining the final property and type information of the target. With the method, firstly, the information utilization rate on the plurality of information sources is enhanced, and the advantages of different information reconnaissance methods are utilized sufficiently; secondly, by a type knowledge base, the relationships of administrative subordination among different level types are established so as to obtain a more specific target type; thirdly, by adopting a DS evidence theory fusing method, prior probability and conditional probability intensity are not needed, and the requirements on preconditions are looser; and fourthly, the comprehensive target identification method can run under different working modes, thereby enhancing the reliability on target identification.

Description

technical field [0001] The present invention relates to a target comprehensive identification method based on uncertain reasoning, which belongs to the field of military avionics technology. Specifically, the present invention is to comprehensively utilize multiple target identities to obtain information and calculate the final target attribute, type and other information to complete target synthesis. identify. Background technique [0002] Target recognition is the most commonly used function in data fusion technology, and it has a wide range of application prospects. It has considerable application requirements in the military field. In recent years, the U.S. military is vigorously developing target recognition technology for battlefield sensing and surveillance systems. In academia, researchers have studied target recognition technology from many aspects, but due to the complexity of the problem itself and the interference of multiple signals, especially the complex elec...
