The Main objective of this paper is to analyze models,techniques,algorithms and infrastructures needed to complete cooperative engagement for warships based on geodetic coordinate system.To increase the performance of maneuvering target tracking,the 2D and 3D target motion models and observation model based on the geodetic coordinate system are derived,by combining the square root-unscented Kalman filter methodology and the information filter framework,two decentralized fusion algorithm denoted as SR-UKF (TR) and SR-UKF (CI) are developed.Theses fusion methods are able to cope with target tracking and fusion problems which arising from intense non-linearity and decentralization in a geodetic coordinate system.The simulation results show the efficiency and robustness of the proposed algorithms with high precision.
