Abstract

Active target tracking systems always suffer from jamming conditions which disturb the proper behavior of their control systems. One of the most effective methods to avoid jamming environment is the TV image tracking of moving targets. TV image tracking is carried out by manually selecting the target to be tracked and then creating proper control signals to the camera via the interface (control unit) to ensure accurate target tracking. This paper proposes a practical TV image tracking system based on Video Blaster as a tool for detecting the target image and converting it into a format suitable for computer processing . In addition, the frame difference window technique is introduced. In this technique, the tracking window is automatically positioned at a predicted target position and the center of this window is considered as the center of the intended target. The hardware interface between the camera and the computer is presented. It was found that, the proposed system overcomes most of the disadvantages of the traditional TV tracking systems, being more stable and reliable.
