Torpedo Test Range Data Fusion Research

This thesis stems from research of torpedo shooting range information fusion and synthesis command & control display system, mainly discusses data fusion problem of the testing system. The work of the thesis is below:1. Discussed the infection of time and interspaced adjusting techniques to shooting range test data.2. Researched two classical data association algorithms: NN and JPDA. Besides, pointed out that in environments existing dense or crossed echo, the two algorithms can lead to wrong result.3. Studied a kind of fast JPDA algorithm to solve the account quantity assembled blasting problem in traditional JPDA algorithm. The simulation shows that it can greatly decrease the numeration, at the same time, it can keep the excellent performance of JPDA.4. Applied EKF algorithm, which is often used in non-linear systems, to the fusion analyzing of torpedo shooting range testing data.5. Based on certain subaqueous weapon's fact system confirmation, a scheme of data fusion used in the shooting range is designed. The simulation result indicated that this scheme is effective and feasible.
