Blind zone of two axes electro-optical tracker in high elevation angle

More Information
  • Tracking error due to the misalignment and lag of a two axes electro-optical tracker with elevation over azimuth configuration in high elevation angle was analyzed. The mathematic method for calculating blind zone induced by this error was given. Misalignment and lag error were simulated in Matlab. The simulation and tracking data indicate that blind tracking zone increases as the elevation angle of the electro-optical tracker increases.
