Abstract: In order to remedy the traditional target reporting, improve the efficiency of target reporting in training of airborneweapon-attacking over the ground, and put forward new method to realize real-time automatic target reporting in battlefields, the design method of the realization of real-time automatic target reporting system for simulant airborneweapon attacking over the ground was put forward by using intersection measurement method theory and adopting CCD imaging principle, image analysis method, the function of pick up all dynamic target, the function of correcting for distortional image, calculation of image threshold and method of focus(center of mass) extraction were solved, and the real-time measurement, caclulation, record and analysysis of hit points were realized. The result of experiment has proved that the capture rate of this system for light spot in the field of view is more than 97%, the relative error of hit points' coordinate is less than 0.23%.
