Passive tracking and size estimation of volume target based on acoustic vector intensity

The special sections of volume target are observed with. acoustic vector intensity according to the difference among their radiated-noise characteristics, then three sections are tracked with Kalman filtering, and target size is estimated. Simulation results indicate that in ideal condition three sections of a ship can be tracked and shipʹs size can be estimated even though one of three sections can not be observed.
