Adaptive Track Fusion for Active/Passive Radar Sensor
Ding Xing-jun, Zhou De-yun · Journal of Projectiles.Rockets.Missiles and Guidance · 2006
An adaptive fusion algorithm is presented based on active/passive radar sensor target tracking.The measurements of the two sensors tracking the same target are processed by linear kalman filters.The outputs of the local trackers are sent to the central node,which contains two index variables with on-line tracking information.The global estimate is obtained by comparison or logic judgments between these index variables and the thresholds.The values of the thresholds govern the trade-off between accuracy and computational burden.Simulation shows that the fusion algorithm has good fusion results.
