As one kind of ground-based satellites tracking instrument, the small optic-electronic satellite tracker executes the mission of searching, capturing, measuring, numbering and monitoring satellites.

This paper has a discussion on the autonomous-capturing target technology of opto-electronic tracker for FCS.

For a fire control system equipping with only opto-electronic tracker and a search radar,the feasibility is proved in theory for calculating the target height through the information supplied by the search radar,such as azimuth,target distance and its range rate,under the premise that the target is at uniform linear motion with equal height.

In the practice of engineering,we used real IR images that were screened by opto-electronic tracker to validate the reliability of the algorithm.

It has highly dependability and feasibility and highly martial application value,and can be used to optimize the software of photo-electricity tracer on the ship.

Analysis and restraining of random noise of optoelectronic tracking system;

System error modification method based on global-function for three-axis optoelectronic tracking system;

Servo control in optoelectronic tracking system is one of the key technologies to realize the high precision tracking.
