In Link 16, track fusion combines data from multiple sources to produce a single, coherent track that includes identity and sensor updates. The best choice says you can fuse PPLI-enabled air and surface surveillance tracks with other sensor reports. That means a track identified with PPLI (identity and platform) can be updated and enhanced by incorporating data from additional sensors (radar, electro-optical, etc.), yielding a more accurate, unified track across air and surface domains. This cross-sensor fusion reduces duplicates and keeps identity consistent across the network, which is the core benefit of fusion. The alternatives aren’t representative of how fusion works: two PPLI tracks aren’t typically merged as distinct identities, tracks aren’t limited to land-only, and EW product information isn’t the type of track data fused into Link 16 tracks.
