Global nearest neighbor (GNN) based target tracking and data association

摘要

The modified GNN/DA subsystem processes angle-only measurements from at least two sensors to reconstruct a complete battlespace picture composed of multiple moving targets (however, using a similar per-sensor track fusion framework as a local track center) can be replicated with n sensors and then fuse them via a multi-local track fusion architecture). In some cases, the sensor is an EO/IR camera and the moving target is a UAV. The modified GNN/DA is used as part of a fire control solution (FCS) implemented onboard to a ground-based vehicle or projectile.
