Target tracking based on the extended line of sight guidance law and information fusion

The extended line of sight (LOS) guidance law is designed to track toward a target in a three-dimensional space, and this method presents a family of guidance laws resulting in a rich behaviour for different parameters. First, polar kinematics models for the pursuer and target are established by taking the observer as a reference point. Second, the extended LOS guidance law was deduced through polar kinematics models. Third, information fusion weighted by matrices was applied to target tracking, providing a good estimate for extended LOS guidance. This combination can enrich the application range of guidance laws and information fusion. Finally, the simulations were implemented in MATLAB. The simulation results confirm the availability of this guidance law.
