Abstract


As science and technology development and modernization needs of the war , information fusion as an emerging cross-disciplinary , in recent years has been widespread attention and rapid development. The multi-sensor multi-target track association methods of research, has been a multi-sensor multi-target tracking and information fusion a hot field . In this paper, a research project , the multi- sensor and multi- target track correlation algorithm conducted in-depth research . The main research work is as follows : 1 , an overview of the basic theory of information fusion of multi-sensor multi-target data association, track correlation methods for summarization and analyzes the characteristics of various association methods ; 2 , in order to improve the traditional navigation track association algorithm associated accuracy , the wavelet transform is introduced into track correlation algorithm, the traditional track correlation algorithm is improved , theoretical analysis and simulation results show that the improved algorithm significantly improves the correct association probability ; 3. based on wavelet framework conditions , the use of wavelet multi-resolution characteristics of the design of a new adaptive track correlation algorithm, which can be well adapted to the maneuvering target and non- maneuvering target track correlation , theoretical analysis and simulation results show that the this algorithm is effective and reasonable , especially for maneuver in the target runtime , the algorithm to better reflect the high probability of correctly associated advantages ; 4, in order for maneuvering target model , this paper also discusses the interactive multiple model ( IMM) method , and the use of uniform motion model and the \test platform , simulation data link system in the whole process of information fusion . The test platform can easily be tested and replacement of the algorithm in order to achieve a variety of algorithms for various combinations of algorithms and performance evaluation .
