Abstract

Tracking accuracy will be improved greatly and stability of control system will not be affected by input velocity of moving target in electro-optical theodolite. However, the velocity of moving target can’t be obtained directly from video or infrared data in electro-optical theodolite. This paper designed two effective forecast filters, Kalman filter and finite-memory smooth filter, to obtain the velocity of moving target. The simulated and test results shows that velocity of moving target can be estimated by fitting the proper position quantity of electro-optical theodolite to the target-missing quantity and using forecast filters. The tracking accuracy of electro-optical theodolite can be improved effectively in this way.
